[comp.dcom.lans] Printing from network via PC PostScript interpreter

regan@cs.Buffalo.EDU (Kenneth Regan) (02/13/90)

This is a blending of queries I've made in comp.lang.postscript and
comp.sys.ibm.pc, after someone suggested I post here.

I have an 80386 PC connected via a "generic" Ethernet card to our local Unix
network (which includes the SparcStation 1 also in my office), and a
Hewlett-Packard LaserJet II.  I will be getting a locally-grown DOS TCP/IP
package for the PC, but have no other software for the card.  I also have
Desqview '386 (a multitasking DOS shell) and some comms software, but I have
nothing specific to DOS-UNIX interchange (such as Rapport).

What I wish to do is add one of the myriad PostScript options which have
sprung up to the LJII, and print from both the PC and the Sparc1.  The 
option which definitely appeals most DP-Tek "PS600" package ($1195 list),
which combines a 600x600 dpi. LJII printer controller (two boards, one for
the printer and one for the PC, connected by the LJII video interface),
and the QMS-Imagen "Ultrascript Plus" software PS interpreter.  

What I have in mind is this: run the TCP/IP software in a Desqview window,
and set up a Desqview process which spools incoming files from the Unix
network and feeds them to Ultrascript.  (After the 5.5MB of extended memory
needed by "PS600", I'll have up to 2.5MB left for the files, plus lots of
hard disk space.)  Reaching for more, I'd like to set up a process on the
Unix end which would let one treat the file-export just like a PostScript
printing device.

	
***  My question is: can this be done (fairly painlessly)?

 
~~~~~~~~~
	Further notes:  Most of the "hardware" options work rather like 
PS600/Ultrascript.  That is, you get two boards which communicate over the
video interface, and software or firmware which turns one of the parallel
ports (LPT2 or LPT3 if not LPT1) into a "smart port", intercepting and
processing any Postscript data which comes to (or through) the port.
(Actually, Ultrascript can be set up to print from within PC applications,
and all including the pure software interpreters can handle saved files.)
My calls to several vendors (QMS, DP-TeK, Hanzon, Abaton/Everex, Princeton
Pub., and CAI ["Freedom of Press" software]) have not turned up much
"network awareness" -- all of these products are spanking new and not many
tests have been done.

	The exception is the Pacific Page LJII cartridge, which does not
involve the PC at all.  One can use a general PostScript  printcap  file
(say, as for an Apple LaserWriter IINT), and hook it directly to the network.
The disadvantage for me is that I'm told (even by Pacific Data) that the
cartridge only accepts soft fonts in Bitstream's format, and wouldn't take
the many scientific soft PS fonts which come with my DOS WYSIWYG text
processor (T-3 from TCI Software Research in New Mexico).  Whether this
can be worked around (say by including the font definitions in every file)
I don't know.

	Thanks in advance for all replies; I will summarize e-mailed ones,
and am curious about general issues this raises for using PC's and Unix
networks cooperatively.  Any partial information is also welcome.

[Disclaimer: I have no commercial connection to any of these vendors, except
for unpaid technical advice to TCI.  Information on all the products mentioned
can be had from recent issues of PC Magazine, PC Week, and InfoWorld.]
