I am posting this here and on comp.sys.mac, not sure which is more
appropriate, but stuff I sent yesterday on comp.sys.mac bounced back to
me so I thought I should send this here also:
As part of my experimentation of using a laserwriterII on the on ethernet
connected to PC's and Mac's I am now testing NCSA Telenet and FTP to send
Mac files dumped in postscript (files created using the k or f key while
printing from particular documents). I am able to create postscript files
that work fine when I dump them to my local laserwriter IINT with the
application SendPs. However when we FTP these files to a MS-DOS system that
is hooked to another laserwriter IINT we get problems. The postscript file
is sent just fine. The second IINT is hooked via the serial port to a net
work of MS-DOS machines. We take these postcript files and "print" them to
the laserwriter IINT, it takes them, the light flashes for awhile then it
stops after a reasonable period, but we get no printout. My question has to
do with what happens to the laserwriter IINT when it is set for the serial
port rather than Appletalk and how it interacts with the postscript files
that we have created on the Mac. Is there a difference in the modes of the
printer when it is set for the serial port that requires some subtle changes
in the postscript files that were transfered from the Mac?? Below I have
included the test postscript file we dumped to the printer from the MS-DOS
serial connection. I have deleted the middle portion with most of the hex
code for the graphics and left all the beggining and trailing postscript
that was created by pressing the "f" or "k" key on my Mac:

Well there is the postcript file that I had created on my Mac. Can any of you
postscript experts out there tell me why it won't print anything on a
laserwriter IINT hooked to MS-DOS machines via the serial port, but will print
fine for a IINT hooked via Appletalk directly to a Mac?? Any input would be
most greatfully appreciated!!!
Thanks in advance for your help!
