	In addition to the higher-speed Postscript printers you mentioned,
namely the Diconix Dijit 1/PS, Dataproducts LZR-2665, QMS PS2400, TI
Omnilaser, and DEC LPS-40, I would give serious consideration to the Imagen
3320/5320/6320/7320 product line.
	We have two Imagen 3320's, both on ethernet, speaking IP/TCP, with the
PS upgrade for PostScript.
	The basic 3320 costs about $20,000 and prints Scribe, TeX, and
lineprinter jobs at 20 ppm.  The ethernet upgrade costs about $2500.  The PS
upgrade costs about $5000, I think.  (You can probably get a better price by
buying the upgrades pre-installed.)  The PS interpreter is about 1-4 times as
fast as our LaserWriter Plus, depending on the document type (typically 4-16
pages per minute).  The print quality (Canon LBP-20) is nicer than a Canon CX,
in my opinion, but people who like the bigger spot-size of the CX and SX won't
like it as much.  The LBP-20 can print on 11" * 17" paper as well as legal and
letter.  You can spend another $20,000 if you want really fancy paper handling
capabilities like duplexing, multiple input and output bins, etc..
	We use Columbia's CAP package on a Sun to spool jobs from macintoshes
for the 3320's.  (This should work for any non-Appletalk PS printer, but the
ethernet connection probably gives higher throughput than serial-line
connected printers.)
	A 68020 version of the controller is rumored.  Imagen has a consistent
history of making upgrades available, so I wouldn't let this rumor cause you
to hold off a purchase.
