The Question is: How do I measure the impact of print queues on overall performance of an OpenVMS cluster? How do I identify bottlenecks? Will moving the print queues to a separate OpenVMS machine print server significantly reduce the load on the cluster nodes? How do I d etermine the memory/disk/input-output/cpu requirements of the proposed print server if it has to handle 200 print queues (distributed over two campuses eight miles apart), 90% of which will be very lightly used? Are there any special interfacing requireme nts for getting OpenVMS print queues (both ascii and postscript) to work with Xerox Document Centre copier/printers? The Answer is : If printing and print queues are a performance-critical factor, your systems are marginally capable -- at best -- of handling your current application environment. (The OpenVMS Wizard is aware of sites with thousands of print queues.) Please see the OpenVMS guide to performance management for details on a systematic approach toward locating and resolving performance-limiting factors. The usual mechanism used for printing to Postscript printers involves the use of the DCPS package. Beyond configuring any necessary transport software (eg: telnet, LAT, serial), no additional software is required for ASCII (or ISO Latin-1) printers. As for what requirements exist for a particular printer, that is something the OpenVMS Wizard would have to determine from the particular printer documentation available. For general IP printing information, please see topic 1020.
