References for OpenVMS users
You can print to your laser printer via the serial interface option from an OpenVMS system, either directly connected to the system or through a network device such as a terminal server.
It is recommended that DECprint Supervisor (DCPS) be used for printing. Please see the "Setting Up Printers" chapter of the DCPS System Manager’s manual for information on creating a DCPS print queue.
If DCPS will not be used, please see the "Setting Up and Maintaining Queues" chapter of the OpenVMS System Manager’s manual for information on setting up print queues using the OpenVMS print sym- biont.
