If the system device control library does not exist, create it.

Enter the INIT/QUEUE command to create the queue itself. Note the addition of the form specifica-
tion and the reset module.

9.1.4 Printing Using DCPS Software
The DCPS software supplied by Digital requires a bidirectional data path. This is only available on the
parallel port if the printer supports the Bitronics extensions to the Centronics interface.
Note:
Autoselecting printers must be locked into PostScript mode for DCPS to work
correctly.
9.1.5 Translating RLAT Jobs to RTEL
The ETS is able to translate RLAT jobs into RTEL jobs to another terminal server. The LAT host and local
ETS should be on the same network, but the remote ETS to which the print device is attached needs only to
be accessible via TCP/IP. This allows LAT print jobs to traverse a router-based network via TCP/IP that
LAT itself would not otherwise be able to. The VMS host uses a print queue on a LAT device as usual, but
the LAT device will have a destination port containing a capital “Q” followed by the name of the print
service on the remote ETS. The destination port is really an environment string. See Environment Strings
on page 2-15 for more information.
On the local ETS, create a virtual service mapping a LAT service to the remote ETS with the attached print
device. When the VMS host forms an RLAT connection to this service on the local ETS, the local ETS will
look at the destination port name and the service name and create an RTEL connection to the remote ETS.
An example setup is displayed below.
