Technical data

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).
Note
DCPS requires that the entire communication path between your
OpenVMS system and your printer be bi-directional. For a networked
printer, this communication path includes the connection between
the printer and the network device as well as the connection between
the network device and your OpenVMS system. LAT and AppleTalk
network devices, and serial interfaces, usually provide bi-directional
communication. Raw TCP/IP network devices, and parallel ports
on a printer, terminal server, or print server, may not satisfy this
requirement. The DCPS software will not work with a connection that
does not allow status messages and other information to be sent from
the printer to your OpenVMS system.
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.
2.1.1 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.
Note
When choosing a baud rate other than the default of 9600 baud,
consider the following limitations:
• OpenVMS drivers do not support baud rates of 3600 and 7200
baud.
• DMZ32 serial interfaces, Revision E or lower, require a speed of
4800 baud or less.
• If you select an improper speed, the printer may not operate or may
stop unexpectedly.
