11.1.3.2 How to Troubleshoot Printer Communications Problems

After determining which system controls the printer port, follow these steps.

Step 1: Check port characteristics

Compare the LAT port characteristics with those listed in the Software Installation GuideSoftware Installation Guide. To view the port characteristics, issue the SHOW PORT command at the Local> prompt or the TSM> prompt.

Step 2: Use procedures in Section 11.1.1

Follow the steps in the appropriate section:

If you follow these procedures and the printer is not printing, go to step 3.

Step 3: Regain control of the LAT port

You may need to disconnect a symbiont process that controls the port connected to the printer. For example, an unsupported version of the symbiont software might not disconnect after it gains control of the port. Disconnect the symbiont process with the following command:


Local> SET PRIVILEGED
Password>
Local> LOGOUT PORT port_number

You need privileged status on the LAT node to execute this command.

11.1.3.3 Common LAT Error Messages

The following list contains common error messages received in a network environment. The error message prefix is DCPS$. The severity level is not indicated. The messages are arranged alphabetically by ident-string. (Refer to the User's GuideUser's Guide for an explanation of the error message format.)

DCPS$_CONAPPLICATION, Connection request is not to a LAT applications port
Explanation: This message usually occurs when a LAT port is not reserved as an applications port, and another device is connected to the port that is requested by the printer. The LAT configuration file LAT$SYSTARTUP.COM should contain a line similar to the following with the /APPLICATION parameter.


SET PORT LTAnnn:/NODE=server-name/PORT=port-name/QUEUE/APPLICATION 

To avoid this problem, specify a higher port number for the printer.

DCPS$_CONTERMINATED, Connection abnormally terminated
Explanation: This message occurs when communication to the LAT node is interrupted. This results in a stopped queue. Check the following:

DCPS$_CONTIMEOUT, Connection timed out, server not available, or incorrect server name specified
Explanation: This message occurs when the server name is not recognized. This problem may indicate the collision of user terminal space and the printer port.

Verify that the server name connected to the printer port is correct. Compare the server name specified in the LAT configuration file LAT$SYSTARTUP.COM with the server name on the LAT device. LAT$SYSTARTUP.COM should contain a line similar to the following:


SET PORT LTAxxx:/NODE=server_name/PORT=port_name/QUEUE/APPLICATION 

Use the SHOW PORT command to find the server name associated with the printer port:


Local> SHOW PORT port-name

DCPS$_LRJACCESSDENIED, Access denied
Explanation: This message usually occurs when the group code specified in LAT$SYSTARTUP.COM does not match one of the groups on the LAT device connected to the printer. Thus, the printer software does not have access to the LAT port. The LAT configuration file LAT$SYSTARTUP.COM should contain a line similar to the following:


SET NODE/GROUP=group-list/ENABLE 

Compare groups, /GROUP=group-list, set in LAT$SYSTARTUP.COM with those set on the LAT device (SHOW PORT command).

DCPS$_LRJDELETED, Queue entry deleted by server
Explanation: This message occurs when someone manually terminates the connection to the LAT device.

DCPS$_LRJILLEGAL, Illegal request parameter
Explanation: This message indicates that an internal LAT error has occurred. Submit a Software Performance Report.

DCPS$_LRJINUSE, Port or service in use
Explanation: This message usually occurs on a LAT port when port-name is not set with the queuing parameter (/QUEUE) enabled or when the queue limit is too small. On the LAT device, enter the following command:


SET PORT port-name QUEUE ENABLE

DCPS$_LRJNAMEUNKNOWN, Port Name is unknown
Explanation: This message occurs when the port name specified in the LAT configuration file LAT$SYSTARTUP.COM is not known on the server. Compare the port name specified in the LAT configuration file LAT$SYSTARTUP.COM with the printer port name associated with the server. LAT$SYSTARTUP.COM should contain a line similar to the following:


SET PORT LTAnnn:/NODE=server-name/PORT=port-name/QUEUE/APPLICATION 

Find the name of the printer port associated with the server, by issuing the following command:


Local> SHOW PORT port-number

DCPS$_LRJNOTOFFERED, Service is not offered on the requested port
Explanation: This message usually occurs when the access mode is not set to REMOTE on the LAT port. Use the SET and DEFINE commands as follows to set the access mode for the port:


Local> SET PORT port-number ACCESS REMOTE
Local> DEFINE PORT port-number ACCESS REMOTE

Note

For more information, refer to the User's GuideUser's Guide or to the troubleshooting guide for your LAT device.

11.1.4 How to Eliminate Excess Login Dialog on Serial Printers

Serial printers transmit unsolicited data to the host system when power-up initialization occurs. The OpenVMS operating system normally interprets unsolicited data from a terminal device as a login request. The printer software startup file sets the SECURE_SERVER terminal characteristic for all printer terminal devices on the host system. SECURE_SERVER prevents the OpenVMS host and the printer from engaging in a potentially endless login dialog.

To eliminate login dialog, set terminal characteristics for terminal devices by using the following procedures in this order:

  1. SYSGEN AUTOCONFIGURE
  2. SYSTARTUP_VMS
  3. DCPS$EXECUTION_QUEUE.COM

AUTOCONFIGURE uses SYSGEN parameters to set default terminal characteristics for all terminal devices on the system. Your system will not encounter the login dialog problem if SECURE_SERVER is set with SYSGEN. The SYSGEN parameter that accomplishes this is TTY_DEFCHAR2. Refer to the OpenVMS Upgrade and Installation Manual for information on setting SYSGEN parameters.

The system startup procedure may also set terminal characteristics. Since this command file executes prior to the printer startup file, your system will be less vulnerable to the login dialog problem if SECURE_SERVER is set for printer terminal devices within the SYSTARTUP_VMS file.

DCPS$EXECUTION_QUEUE.COM (the printer execution queue command file) sets the SECURE_SERVER terminal characteristic for printer terminal devices by default. This file is provided in the software kit.

If your printer is configured on a LAT device in a local area Ethernet, set the LAT port and the terminal server characteristics for the printer to minimize login dialog. Refer to the Software Installation GuideSoftware Installation Guide for LAT port characteristics.

11.2 What to Do if a PrintServer Printer Is Not Printing

The following troubleshooting procedures can help you diagnose error conditions that can occur during installation of DECprint Supervisor software for PrintServer printers.

If the printer is not printing, check the OPCOM messages. If the cause of the failure is not immediately apparent, check the queue characteristics, as follows:

  1. Execute the following instruction, inserting the name of the PrintServer device queue:


    $ SHOW QUEUE queue-name/FULL
    

    For example, the queue characteristics for the PrintServer device queue LPS40$FANG on node VIPER are as follows:


    $ SHOW QUEUE LPS40$FANG/FULL
    


    Printer queue LPS40$FANG, on VIPER::FANG, mounted form DCPS$$FORM 
    (stock=DEFAULT) 
        /BASE_PRIORITY=4 /FORM=DCPS$DEFAULT /LIBRARY=DCPS_LIB /OWNER=[SYSTEM] 
        /PROCESSOR=DCPS$SMB /PROTECTION=(S:E,O:D,G:R,W:W) /SCHEDULE=(NOSIZE) 
        /SEPARATE=(FLAG,TRAILER) 
    $ 
    

  2. If the queue characteristics do not match those recorded in DCPS$STARTUP.COM, delete the device queue and all generic queues that point to it. Then execute the DCPS$STARTUP.COM file. DCPS$STARTUP is located in SYS$STARTUP:. For example:


    $ STOP/RESET/QUEUE generic-queue-1
    $ STOP/RESET/QUEUE other-generic-queues
    $ STOP/RESET/QUEUE pserver-name
    $ DELETE/QUEUE generic-queue-1
    $ DELETE/QUEUE other-generic-queues
    $ DELETE/QUEUE pserver-name
    $ @SYS$STARTUP:DCPS$STARTUP
    

    Recheck the queue characteristics. If they are correct and the job still does not print, refer to the DEC PrintServer Supporting Host Software for OpenVMS Management Guide for further information.

11.3 What to Do if Printing Is Slower than Expected

Slower printing speeds can result from:

Complex ANSI jobs include those that use many downloaded fonts on a page. These jobs always take longer to print.

For serial printers, a 30-second delay before the printing of ANSI jobs indicates an ANSI prologue mismatch between the ANSI translator and the print job. On a serial printer, power cycle the printer (turn it off and then on) to load the appropriate prologue. The first ANSI print job is delayed by the loading of the prologue, but subsequent ANSI print jobs are printed more efficiently.

If your printer is connected to multiple nodes running different versions of the printing system, power cycling the printer may not eliminate the 30-second delay. The node that connects to the printer first persistently loads its prologue. The other nodes must load the prologue with every print job. To eliminate the delay in this case, every node should run the same version of the DECprint Supervisor software.

11.4 What to Do if Layup Definition Files Are Not Found

DECprint Supervisor software places the following sample layup definition files in [SYSHLP.EXAMPLES.DCPS]:

LPS$HOLES.LUP
LPS$SINGLEHOLES.LUP
LPS$DOUBLEHOLES.LUP
LPS$NUP.LUP
COLOR-PRINTER-FULL-PAGE.LUP
PROPRINTER-FULL-PAGE.LUP

Make sure that the layup directory logical name, DCPS$LAYUP, points to SYS$SYSDEVICE:[SYSHLP.EXAMPLES.DCPS] or to the directory that contains the .LUP sample files on all nodes in the cluster.

11.5 What to Do if Files Are Printed with Unexpected Results

The DECprint Supervisor software attempts to print every file in every print job even if there are problems in the specification of print parameters and print job attributes. Print queues with erroneous default parameters can still print files, but all the print parameters are not effective and messages are generated indicating the problem, as described in Section 11.5.1.

In cases where the file is printed using the wrong data type translator, the file data type has not been correctly determined by the DECprint Supervisor software. The methods for solving problems with automatic data type detection are described in Section 11.5.2.

11.5.1 What to Do if Default Queue Parameters Are Not Effective

If you enter a parameter in DCPS$STARTUP.COM incorrectly, print jobs sent to that print queue are printed, but the invalid parameter and the parameters following it are not applied to the print job.

If an invalid print parameter is included in the queue definition, the printing system generates an error message that is displayed on your screen and printed on the job trailer page for every print job sent to the associated queue. The parameters that are not processed take the default settings.

In the following example, there is an extra L in the argument to the second parameter, PAGE_ORIENTATION. Therefore, the printing system ignores the second parameter, NUMBER_UP=2. Only the first parameter, SHEET_SIZE=B, is processed.


@sys$startup:dcps$generic_queue -     ! Landscape queue 
     DCPS$WIDE$PRINT -                ! P1 - Generic queue name 
     TEK4014_TTB4 -                   ! P2 - /GENERIC = execution queues 
     "SHEET_SIZE=B,PAGE_ORIENTATION=LLANDSCAPE,NUMBER_UP=2" 
                                      ! P3 - Default queue parameter 
                                      ! P3 - Default queue parameter 

For every print job for this queue, an error message similar to the following is displayed on the screen and printed on the job trailer page in the message section:


10-MAR-2001 15:21 %DCPS-E-PARSYNERR, Syntax error in the /PARAMETERS 
qualifier at or near PAGE_ORIENTATION=LLANDSCAPE 

11.5.2 What to Do if a File Data Type Is Not Recognized

If the DECprint Supervisor software fails to determine the data type of a print file correctly, the user can explicitly specify the DATA_TYPE parameter. If necessary, you can set up a generic queue for specific data types. All files printed to this queue will have the specified data type, unless the user explicitly specifies another data type using the DATA_TYPE parameter. Users can also specify the DATA_TYPE=AUTOMATIC parameter to explicitly specify automatic data type detection.

The automatic data type feature examines the following to determine the data type of the file:

  1. The value of the DATA_TYPE parameter in the PRINT command
  2. The queue default data type specified in the DCPS$STARTUP.COM file
  3. OpenVMS file tags (for example, DDIF stored_semantics tags)
  4. The contents of the file
  5. The file extension

If the DECprint Supervisor software cannot determine the file data type from these steps, the default text data type is used. If no default text data type has been defined by the user or the system manager (see Section 4.2.2), the file is processed as ANSI. When the default text data type is used, the text can precede PostScript; the file is printed properly. However, the file may not be printed properly if any more text follows the PostScript data. In this case, it may be necessary to edit the file and print the text and PostScript data as separate files.

In general, though, users should not be encouraged to modify the contents of their files or the file extensions so that the data type can be determined. Instead, the application that generates the file may be examined and modified if necessary; or you can provide site-specific file extension files, default text data types, or generic queues with explicit default data types.


Appendix A
Printing System Management Commands

You use standard OpenVMS DCL commands to manage the DECprint Supervisor queues, jobs, and related system resources.

Note

Remember that the management commands only affect the system on which they are issued. A network printer can serve other systems as well, with each system having its own set of queues, jobs, forms, etc.

A.1 Overview of Management Commands

Table A-1 lists the commands used to manage print queues, print jobs, and related system resouces. More information for these commands can be found in the OpenVMS DCL Dictionary.

Table A-1 Printing System Management Commands
Command Function
ASSIGN /MERGE Removes jobs from one queue and puts them in another existing queue.
ASSIGN /QUEUE Assigns a logical queue to an execution queue.
DEASSIGN /QUEUE Deassigns a logical queue and stops the logical queue.
DEFINE /CHARACTERISTIC Defines a queue characteristic name and number.
DEFINE /FORM Defines a printer form name, number, and attributes.
DELETE /CHARACTERISTIC Deletes the definition of a queue characteristic.
DELETE /ENTRY Deletes one or more job entries from a queue.
DELETE /FORM Deletes the definition of a form.
DELETE /QUEUE Deletes a queue.
INITIALIZE /QUEUE Not recommended for use with the DECprint Supervisor software.
SET ENTRY Changes or deletes attributes of a job that is in the queue but not currently executing.
SET QUEUE Changes the status and attributes of a queue.
SET QUEUE /ENTRY This command has been superseded by the SET ENTRY command, which performs identical functions. Compaq recommends that you use the SET ENTRY command.
SET QUEUE /RETAIN Retains print jobs upon completion or termination due to an error.
SHOW ENTRY Display information about print jobs.
SHOW QUEUE Displays information about queues and jobs.
SHOW QUEUE /CHARACTERISTICS Displays information about queue characteristic names and numbers available on a queue.
SHOW QUEUE /FORM Displays the names and numbers of the forms defined for your system.
START /QUEUE Starts or restarts a queue.
START /QUEUE /MANAGER Starts the system job queue manager and opens the queue file.
STOP /QUEUE Pauses an execution queue.
STOP /QUEUE /ABORT Stops the executing print job, but does not stop the queue.
STOP /QUEUE /MANAGER Stops the system job queue manager and closes the job queue file.
STOP /QUEUE /NEXT Stops the queue after the current job has finished printing.
STOP /QUEUE /REQUEUE Stops the executing print job and requeues it to the specified queue, but does not stop the queue.
STOP /QUEUE /RESET Stops a queue immediately and returns control to the system.

A.2 Use of SET PRINTER with DCPS

Because PostScript printers are controlled by the DECprint Supervisor software, the DCL SET PRINTER command has no meaning in a DECprint Supervisor environment. Print job characteristics for the DECprint Supervisor are set and displayed by other means.

Print job characteristics for DECprint Supervisor are determined by:

  1. Parameters embedded in the job data
  2. Parameters passed in the /PARAMETERS qualifier of the PRINT command
  3. DEFINE /FORM qualifiers
  4. For PrintServer printers, default parameters which are in the PrintServer configuration database
  5. The default queue parameters, which are defined in the DCPS$STARTUP.COM file

Items 1, 2, and 3 in this list are controlled by the PostScript interpreter or the data syntax translator, depending on the type of job being processed. Item 4 is controlled by the PrintServer server management interface described in the DEC PrintServer Supporting Host Software for OpenVMS Management Guide.

Table A-2 shows the SET PRINTER qualifiers and the equivalent control in a DECprint Supervisor printing system.

Table A-2 SET PRINTER Qualifier Equivalents for DECprint Supervisor Queues
SET PRINTER Qualifier Equivalent Control
/CR Insertion of carriage return characters is controlled by the current data type translator.
/FALLBACK Translation of DIGITAL multinational characters is controlled by the current font. If the character does not exist in the specified font, the font error character prints.
/FF Mechanical form feeds are controlled by the current data type translator or the PostScript interpreter.
/LOWERCASE The DECprint Supervisor printer is considered to be a lowercase printer. It does not translate lowercase to uppercase.
/PAGE The number of lines printed on each page is controlled by the ANSI translator (ANSI files only). This characteristic is available through DEFINE /FORM.
/PASSALL Whether the system interprets special characters or forwards them as 8-bit binary data is controlled by the current data type translator.
/PRINTALL Whether the printer interprets special characters or prints their 8-bit binary equivalent is controlled by the current data type translator.
/TRUNCATE Truncation of data that exceeds the limitation imposed by the /WIDTH qualifier is controlled by the form definition or the current data type translator.
/WIDTH The number of characters allowed on each line of the currently installed media is controlled by the form definition, or a combination of the current data type translator and the current font.
/WRAP Generation of a carriage-return/line-feed by the printer when it reaches the end of a line is controlled by the form definition or the current data type translator.

Note

Not all data type translators implement the preceding functions in the same manner; refer to a translator's documentation for specific information about its behavior.
