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.

1. Edit LAT$SYSTARTUP.COM and add the following command to create an applications port on the host node (service node) that will support your printer:

   $ CREATE PORT LTAd:/NOLOG/APPLICATION

   
   In this command format, you supply the number of the applications port for d, which must be a unique number from 1-9999.

   Note 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.

   
   
2. In LAT$SYSTARTUP.COM, add the following command to associate the applications port with a remote port on a server:

   $ SET PORT LTAd:/NODE=server_name/PORT=port_name/QUEUE/APPLICATION

   
   In the command format, you supply the following values:

   LTAd:	Name of the application port
   server_name	Name assigned to the LAT device
   port_name	LAT device's port name

   
   The following example associates application port LTA9000: with port PORT_7 on a remote DECserver 200 named LN03RDS:

   $ SET PORT LTA9000:/NODE=LN03RDS/PORT=PORT_7/QUEUE/APPLICATION

   
   If the LAT device is dedicated to printing services, you can define the LAT connection for the printer in the DCPS$STARTUP.COM file. This makes it easier for you to solve configuration problems because all the information is in one file. However, if the LAT device also supports devices other than printers, you should define the port in the LAT$SYSTARTUP.COM file.

3. To make a successful LAT connection, you must make sure the following lists of groups have at least one LAT group in common:
   • On the LAT port, authorized groups and current groups
   • On the service node, enabled groups
   
   If you did not set up these groups correctly, you receive the following error message when a print job is submitted:

   %DCPS-E-LRJACCESSDENIED, Access denied

   
   You can use LATCP commands to include the necessary LAT group designations. For additional information, refer to the OpenVMS System Management Utilities Reference Manual.

   Note 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:

1. Set the printer to the appropriate baud rate (see your printer hardware installation guide).
2. Set the DECserver communications speed (see your terminal server installation guide).
3. Power on the printer. Wait for the printer to eject the power-up test page, and then check the test page to ensure that the desired settings are indicated on the test page.

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.

2.1.3 General Information

You can use DCPS with many PostScript printers. Consult the SPD for the list of supported by the DECprint Supervisor software. 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:

• Install a PostScript option if your printer requires one.
• Install at least the minimum amount of memory for PostScript printing.

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. Compaq 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.

2.2 DIGITAL PrintServer Printers

DIGITAL PrintServer printers are network printers. They require the OpenVMS DECnet, Compaq TCP/IP for OpenVMS, Process Software MultiNet for OpenVMS or Process Software TCPware for OpenVMS software to be running on the OpenVMS systems where the DECprint Supervisor software is running.

The following procedures allow users to access PrintServer printers on TCP/IP and DECnet networks.

2.2.1 Defining PrintServer TCP/IP Network Nodes

Before you can communicate with your DIGITAL PrintServer printer via TCP/IP, you must assign an IP address to it. You may also associate a name with the address.

Refer to the PrintServer documentation for information on setting the printer's IP address. Refer to Compaq TCP/IP Services for OpenVMS, Process Software MultiNet for OpenVMS or Process Software TCPware for OpenVMS documentation for information on configuring your OpenVMS system's TCP/IP environment.

2.2.2 Defining PrintServer DECnet Network Nodes

Before you can communicate with your DIGITAL PrintServer printer via DECnet, you must assign a DECnet address to it. You may also associate a name with the address.

Refer to the PrintServer documentation for information on setting the printer's DECnet address.

To associate a DECnet node name name with the printer's DECnet address, use the NCP command if you are running DECnet Phase IV software, or the DECNET_REGISTER command if you are running DECnet-Plus (formerly DECnet/OSI) software. Refer to the OpenVMS DECnet documentation for more information about node names and these commands.

2.2.3 Deleting the PrintServer Client Startup File

An existing LPS$STARTUP.COM file, if any, is no longer used and is not compatible with DECprint Supervisor. Delete this file after you edit DCPS$STARTUP.COM. To delete this file, follow this procedure:

1. Stop existing print queues with the STOP/QUEUE/RESET command.
2. Delete existing PrintServer print queues.
3. Add new print queues to DCPS$STARTUP.COM for PrintServer printers.
4. If you have any customized definitions in the LPS$STARTUP.COM file, copy the changes into SYS$STARTUP:DCPS$STARTUP.COM.
5. Edit SYS$MANAGER:SYSTARTUP_VMS.COM, removing the reference to SYS$MANAGER:LPS$STARTUP.COM.
6. Delete LPS$STARTUP.COM. You can delete this and other files that are no longer needed for PrintServer printing using the following command file: SYS$COMMON:[SYSHLP.EXAMPLES.DCPS]DCPS$DELETE-LPS-CLIENT.COM

This chapter explains how to start up the printing system and test the printer.

If this is a new installation, you can use the startup template file to help you set up your queues. Copy the printer startup template file as follows:

$ COPY SYS$COMMON:[SYS$STARTUP]DCPS$STARTUP.TEMPLATE - SYS$COMMON:[SYS$STARTUP]DCPS$STARTUP.COM

3.2 If You Are Upgrading From DECprint Printing Services Software (CPS)

If you are upgrading from CPS to DCPS, convert your CPS$STARTUP.COM file as follows:

1. Enter the following command:

   $ @SYS$STARTUP:CPS_TO_DCPS_STARTUP.COM

2. Answer the questions displayed on your screen. For example:

   Enter filename of CPS startup file to be converted; Default filename is SYS$SYSROOT:[SYS$STARTUP]CPS$STARTUP.COM [default]: disk$manager:[cps_conversion]cps$startup.com Enter filename of DCPS startup file to be created; Default filename is SYS$SYSROOT:[SYS$STARTUP]DCPS$STARTUP.COM [default]: disk$manager:[cps_conversion]dcps$startup.com Please read or run DIFFERENCES on the output file, DISK$MANAGER:[CPS_CONVERSION]DCPS$STARTUP.COM, to be sure the new file meets your needs.

The procedure creates a startup file that DECprint Supervisor recognizes, but does not change your existing queue definitions. If you need to add new queues, see Section 3.3

DCPS has an automatic data type detection feature. Therefore, you no longer need to specify the data type as a queue default or in the PRINT command.

If you defined generic queues for default data types, edit
DCPS$STARTUP.COM and remove them.

3.3 Setting Up Execution Queues

You must create an execution queue for each PostScript printer. Execution queues schedule jobs for processing and deliver the print jobs to a printer. An execution queue is associated with a particular printer.

When you create an execution queue, you supply information about the queue, including its name and default parameters. Example 3-1 shows creation of an execution queue for a PrintServer printer. Example 3-2 shows creation of an execution queue for a serial printer. These commands are placed in DCPS$STARTUP.COM.

Example 3-1 Creation of an Execution Queue Entry for a PrintServer Printer

$ @SYS$STARTUP:DCPS$EXECUTION_QUEUE - LPS20$BULL09 - ! P1 - Execution queue name "DECNET/BULL09" - ! P2 - Device name (PrintServer DECnet node name) DCPS_LIB - ! P3 - Logical name for your library search list "SIDES=2" - ! P4 - Defines a default queue parameter "" - ! P5 - Value to override/add to default qualifiers "" - ! P6 - Communication speed "" - ! P7 - Set device qualifier "" ! P8 - Verify on/off

Example 3-2 Creation of an Execution Queue Entry for a Serial Printer

$ @SYS$STARTUP:DCPS$EXECUTION_QUEUE - 2UP - ! P1 - Execution queue name "SERIAL/TTB4" - ! P2 - Device name DCPS_LIB - ! P3 - Logical name for your library search list "NUMBER_UP=2" - ! P4 - Defines a default queue parameter "/DEFAULT=(FLAG,FORM=MYFORM,NOFEED)" - ! P5 - Value to override or add to default qualifiers "" - ! P6 - Communication speed "/SPOOL=(2UP,DISK1$:)" - ! P7 - Set device qualifier "" ! P8 - Verify on/off

The following sections describe each item of information you need to supply to DCPS$EXECUTION_QUEUE.COM.

3.3.1 Supplying the Name of the Execution Queue (P1)

An execution queue name can have 1-31 characters, including uppercase and lowercase alphabetical characters, digits, the dollar sign ($), and the underscore character (_). The queue name must include at least one alphabetical character and cannot have intervening spaces.

3.3.2 Supplying the Printer Device Name (P2)

The printer device name specifies the interconnect and device used to access the printer, and the VMScluster member node on which it resides.

Specify the device name in the following format:

node::"interconnect/interconnect_specific_device_address"

where:

• node is the name of the VMScluster member on which the queue executes. If the OpenVMS system is not a member of a cluster, then node:: can be omitted.
• interconnect specifies the interconnect type. You can specify one of the following:

  For ...	Specify ...
  Printers that connect through raw TCP/IP sockets	IP_RAWTCP
  Printers that connect directly or through LAT	SERIAL
  PrintServer printers using CPAP protocol and DECnet	DECNET
  PrintServer printers using CPAP protocol and TCP/IP	IP_CPAP
  Printers that connect through EtherTalk and LocalTalk protocols	APPLETALK

• interconnect_specific_device_address is the actual address of the printer.

The following sections have specific instructions:

For Printer using this interconnect...	See ...
IP_RAWTCP	Section 3.3.2.1
Serial	Section 3.3.2.2
IP_CPAP	Section 3.3.2.3
DECnet	Section 3.3.2.4
AppleTalk	Section 3.3.2.5

3.3.2.1 If Your Printer Is On a TCP/IP Network and Uses Raw TCP/IP Sockets

Enter the device information in the following format:

"IP_RAWTCP/address:port"

where:

address is the IP address of your NIC, print server, or terminal server in either a named or numeric format.

port is the number of the raw TCP port for your network device. Check the documentation for your NIC, print server, or terminal server to determine what number to use. Table 3-1 shows the port numbers for some commonly-used devices.

Table 3-1 Raw TCP/IP Port Numbers

	20nn	DECserver terminal servers, where "nn" is the physical port number
	2501	DIGITAL LN17ps and DIGITAL Laser Printer LN17+ps
		Emulex NICs
	3001	DIGITAL Laser Printer LN15 and LN15+
		DIGITAL RapidPrint 500 print server
	6869	DIGITAL Laser Printer LN20, LN40 and LNC02
	9100	Compaq Laser Printer LN16, LN32 and LNM40
		GENICOM LN and microLaser printers
		GENICOM RapidPrint MPS100 print server
		Hewlett-Packard LaserJet printers
		Lexmark Optra printers
		Tektronix Phaser printers
		Xerox DocuPrint N printers
		Hewlett-Packard JetDirect, XCD, and Lexmark NICs

For example, a raw TCP/IP printer could be specified by either of the following:

"IP_RAWTCP/ln17ps.my.org:2501" "IP_RAWTCP/8.9.10.11:2501"
