[comp.os.vms] questions on DEC's LPS20 and QMS's 6320

Comments on DEC's Printserver 20 (LPS20) and/or QMS's 6320.
-----------------------------------------------------------

	We are in the process of evaluating 20-30 ppm postscript 
printers for a central printing facility on campus. We have narrowed 
our choices down to DEC's Printserver 20 and QMS's 6320. I'm interested
in getting some feedback from anyone who has used either of these 
printers. Some of the questions I have are -

	- Do the printer supplies meet their rated life time?
	- Print quality degradation. As printer supplies reach there
	    rated life, does the quality steadily get worst, or does
	    quality stay good up until the supplies reach there expected 
	    life, then drop off quickly?
	- How's the reliability of the printer if running close too,
	    but not exceeding it's monthly duty cycle?
	- Who do you use for service, and how would you rate them?  
	- Error handling. 
	    Does the printer or symbiont hang when it comes across something
	      in a files it doesn't know what to do with? or does it print
	      an error and move on to the next job?
	    What type of diagnostics are available either on the printer,
	    or a printer/software combination?
	- Speed Ratings.
	    How much does the printer slow down when printing fairly complex 
	      postscript jobs, or graphics, as compared to printing straight 
	      text?
	- Paper handling.
	    How well does the printer organize job seperation? Are differant
	      input trays easily callable from your print jobs, or is some
	      operator intervention required?

	Thanks in advance for any comments on the these printers. If anyone 
is using some other postscript printer rated between 20 and 30 ppm that's
running close to it's duty cycle and is happy with it's performance, I'd
be interested in hearing more about that printer. Ethernet, duplex, 300 dpi
or better, and large input and output paper capabilities are pretty much our
requirements.
