If you are installing DECprint Supervisor for the first time, or installing new printers, read this chapter. You may also find this chapter useful if you are changing the setup of an existing printer. The following sections describe how to set up your printers to work with DECprint Supervisor software.
Non-PrintServer printers | Section 2.1 |
DIGITAL PrintServer printers | Section 2.2 |
If you are changing the setup of a printer for which a DCPS queue already exists, you must first stop the associated queue using the STOP /QUEUE /NEXT or STOP /QUEUE /RESET command. |
You can connect PostScript printers other than DIGITAL PrintServer printers to your OpenVMS system in a number of ways:
If your printer is connected via the network, multiple systems can access it.
The devices that can be used with DECprint Supervisor software are listed in the Software Product Description (SPD).
Your printer may contain a network interface card (NIC) or may be accessable to the network via a print server of a terminal server.
Printers can be configured as network printers if:
Network printing has the following implications:
Raw TCP/IP is a network protocol that utilizes the TCP/IP protocol directly without any additional interpretation of the TCP data stream. It is supported by many printer Network Interface Cards (NICs), print servers, and terminal servers.
There are other printer protocols that layer upon TCP/IP, including CPAP (Common Printer Access Protocol), LPD, and Telnet. DCPS uses CPAP to communicate with DIGITAL PrintServer printers.
DCPS does not support the Telnet or LPD protocols. |
To communicate with your printer using raw TCP/IP, the NIC, print server, or terminal server that you use to connect your printer to the network must provide a raw TCP/IP port. Further, this raw TCP/IP port must support bi-directional communication between the printer and your OpenVMS system. DCPS does not work with unidirectional ports, such as those found on the NICs for the DEClaser 3500 and 5100 printers, the RapidPrint 200, and Hewlett-Packard JetDirect cards that interface with the printer via its XIO (versus MIO) slot.
Before you can communicate with your printer via TCP/IP, you must
define an IP address for it. You may also assign a name to the address.
Refer to the printer documentation for information on setting the
printer's IP address. Refer to HP TCP/IP Services for OpenVMS, Process
Software MultiNet for OpenVMS, or Process Software TCPware
documentation for information on configuring your OpenVMS system's
TCP/IP environment. If your printer is connected through a print server
or terminal server, you must configure the IP address of the server.
You also need to configure the connection between the printer and the
server (for example, you may need to perform actions similar to those
described in Section 2.1.1.2.2 for LAT printers). Refer to documentation for
your terminal server or printer server for information on configuring
its network and printer interfaces.
2.1.1.2 LAT Printers
2.1.1.2.1 Configuring the Printer for LAT Access
To configure serial printers as network printers through a LAT connection to the Ethernet, change the following:
You can also change the printer password and printer name. These
changes are optional and explained in Section 2.1.3.3 and Section 2.1.3.4.
2.1.1.2.2 Setting DECserver LAT Port Characteristics
The process for configuring non-DECserver LAT devices is not described here, but many LAT devices use the same commands used by a DECserver device. Refer to the online help or other documentation for your NIC, terminal server, or print server for more information. |
To change DECserver port characteristics, you need privileged status on the DECserver device. Once you have privileged status, use the DEFINE PORT and SET PORT commands.
The DEFINE command changes the port's characteristics in the server's permanent database. These changes do not take effect until the next login for the port.
SET commands take effect immediately, but only alter the port's characteristics for the current session. For example, to change the INPUT SPEED and OUTPUT SPEED values on PORT_6 to 19200 baud (on a DECserver 200), issue the following commands from the console server manager:
LOCAL> SET PRIVILEGED PASSWORD> password LOCAL> SET PORT 6 SPEED 19200 LOCAL> DEFINE PORT 6 SPEED 19200 |
DECprint Supervisor supplies a sample command file for this purpose, if using LAT. This command file sets the characteristics for a DECserver with the Terminal Server Manager (TSM) software, and records data in the TSM database. (TSM is a software product available separately from HP.) The command file is:
This command file provides examples of characteristics for DECserver 100, DECserver 200 and DECserver 500 devices. |
For information about the commands and procedures for your DECserver device, refer to your DECserver management guide.
Make sure the DECserver port characteristics match the settings on your printer. Table 2-1 and Table 2-2 list DECserver port characteristics that must match the settings on your printer.
Character size | 8 |
Parity | None |
Input speed | 9600 |
Output speed | 9600 |
Make sure the queue limit is not set to 0, which disables queuing.
Characteristic | Default Settings |
---|---|
ACCESS | REMOTE |
AUTOBAUD | DISABLED |
AUTOCONNECT | DISABLED |
AUTOPROMPT | DISABLED |
BREAK | DISABLED |
BROADCAST | DISABLED |
FLOW CONTROL | XON |
INPUT FLOW CONTROL 1 | ENABLED |
OUTPUT FLOW CONTROL 1 | ENABLED |
INACTIVITY LOGOUT | DISABLED |
LOSS NOTIFICATION | DISABLED |
MESSAGE CODES | DISABLED |
QUEUING | ENABLED |
VERIFICATION | DISABLED |
On many versions of DECserver devices, QUEUING is not a port characteristic, but is a server characteristic whose default is ENABLED. |
The LAT configuration file (SYS$STARTUP:LAT$SYSTARTUP.COM) defines host node service characteristics. Before you start the print queues, make sure the LAT driver is running and ports are available.
Commands referenced in this section are LATCP commands. For more information on LATCP commands, refer to the OpenVMS System Management Utilities Reference Manual. |
$ CREATE PORT LTAd:/NOLOG/APPLICATION |
LTA devices are not always dedicated to printers; they may be shared with other devices. Connections to the LTA device from the other devices are established dynamically among the lowest available ports. If you assign a higher port number to the printer, you can help secure the port for the printer and prevent interference from connections to other devices. |
$ SET PORT LTAd:/NODE=server_name/PORT=port_name/QUEUE/APPLICATION |
LTAd: | Name of the application port |
server_name | Name assigned to the LAT device |
port_name | LAT device's port name |
$ SET PORT LTA9000:/NODE=LN03RDS/PORT=PORT_7/QUEUE/APPLICATION |
%DCPS-E-LRJACCESSDENIED, Access denied |
This information is not required for the DECserver 90L device. |
Make sure the serial printer communications speed is set to the default (9600 baud). If you want the printer to run at a different baud rate, use the following procedure.
If the printer is on a DECserver device, use the following steps:
If you use your printer in an AppleTalk network, the address of the
printer in the AppleTalk network is normally the printer's PostScript
printername. If two or more printers have the same printername and are
on the same zone of the AppleTalk network, the actual node names for
these printers will be depend on the order in which the printers are
powered up. Printers of the same product type will have the same
printername until it is explicity changed. Therefore, it is necessary
to change a printer's printername to ensure the printer is uniquely and
consistently identified on the network. Use the tools provided with
your printer, and/or your PC or Macintosh to change the name of your
printer.
2.1.2 Directly-Connected Serial Printers
For your printer and OpenVMS system to be able to communicate, you must set the baud rate of your printer and system's serial interfaces to the same values. Also, your printer should be set for eight-bit characters with no parity.
When choosing a baud rate other than the default of 9600 baud, consider the following limitations:
|
Refer to your printer's hardware installation guide for information on configuring its serial interface. After you have made the necessary changes, turn the printer off and back on. Then manually print a test page and verify that the reported settings are as desired.
Set the baud rate of your OpenVMS system's serial interface by specifying a value for P6 when setting up the corresponding DCPS print queue, as described in Section 3.3.6.
CSA0: (printer port 0 on VAXstation II and VAXstation II/GPX systems) is not a supported interface for serial printers. DEClaser printers may require an H8571--E adapter if you are using a DECconnect serial cable. Refer to your printer installation guide for more information. |
You can use DCPS with many PostScript printers. Consult the SPD for the list of supported printers. You may also be able to use DCPS in an unsupported fashion with printers not listed in the SPD (see Section 7.12).
Before installing a printer, perform the following:
Printing legal size paper or printing duplex requires more memory than
the base configuration. Consult your printer manual for your minimum
requirements.
2.1.3.2 Setting the printer timeout
The printer may abort a print job if it does not receive data for a specified period of time. HP recommends that you change the timeout value to zero (0), which means no timeout.
You may be able to set the timeout value through the front panel, as documented in the operator's guide for your printer.
You can also change the printer timeout value with the setdefaulttimeouts PostScript operator. Modify the standard file SYS$COMMON:[SYSHLP.EXAMPLES.DCPS]LPS$SET_TIMEOUT.PS to change the timeout value to 0. Print the file using the DATA_TYPE=POSTSCRIPT parameter to change the timeout value in the printer's nonvolatile memory to 0, thus preventing timeout conditions on the printer.
To submit the file for printing as a PostScript job, use the following command:
$ PRINT/QUEUE=queuename/PARAMETER=(DATA_TYPE=POSTSCRIPT) LPS$SET_TIMEOUT.PS |
When the print job is processed, a page is printed to indicate that the
timeout was successfully changed.
2.1.3.3 Changing the Printer Password
PostScript printers have passwords that restrict access to certain functions. You can change the password for your printer from the default value. For serial printers, submit a print job that includes the current password as well as the new password. Refer to the PostScript Printers Programmer's Supplement for information about changing your printer's password.
The default password for ScriptPrinters is (LN03R), with the
parentheses required. The default password for DEClaser printers is 0
(the number zero), without parentheses. If you change the printer
password from the default, print jobs may take longer to print, because
the printer password is required to persistently load PostScript
prologues for ANSI files and separation pages.
2.1.3.4 Setting the Printer Name
Some system messages include the printer name. If you have not set a unique printer name, these messages contain the default printer name. The default printer name for a ScriptPrinter printer is LN03R. The default printer name for a DEClaser printer is DEClaser. For example, on a DEClaser printer where the name has not been changed, the following message reflects the default printer name:
%DCPS-I-TRAYSUBST, Output will be delivered to the only tray on DEClaser |
If you change the DEClaser printer name to SNUFFY, the same error message reflects the unique new printer name:
%DCPS-I-TRAYSUBST, Output will be delivered to the only tray on SNUFFY |
For non-PrintServer printers, the printer name is stored in the printer's nonvolatile memory. To set the printer name, edit a copy of the file LPS$SET_PRINTER_NAME.PS found in SYS$COMMON:[SYSHLP.EXAMPLES.DCPS] to include the desired name and password. Select a printer name of 31 characters or less.
Then submit the file for printing as a PostScript job:
$ PRINT/QUEUE=queuename /PARAMETER=(DATA_TYPE=POSTSCRIPT) - LPS$SET_PRINTER_NAME.PS |
Edit and submit a copy of LPS$SET_PRINTER_NAME.PS for each printer that requires a unique name.
