Technical data

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.

2.1.2 Networked Printers

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:

• The printer is connected to a NIC, print server, or terminal server.

• Every host system using the printer is running DECprint Supervisor

software. If any host system accesses the printer by any other means, the

printer system may fail.

Network printing has the following implications:

• The printer may be used from multiple systems.

• There is no centralized accounting for the printer. Each system maintains

separate accounting information for the printing performed by that system.

• Multiple systems running DECprint Supervisor software contend for the

same printer.

• There is no centralized print queue for the printer, which means:

The SHOW QUEUE command does not display the queues located on

other nodes in the network.

The system does not provide print job scheduling or load balancing

among printers or nodes in the network.

2.1.2.1 Raw TCP/IP Printers

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.
