Patrick,
Thanks to your "shutdown_appsocket" flag in ifhp-3.4.1 I can get both of
my Phaser 850s(dp & dx) to work! Prior to this, whenever I printed a test
page from a Win98 PC I got the expected text & graphics followed by
postscript errors. The PCs use the latest & greatest 850(dp/dx) drivers
from Xerox. Yet, both text & graphics printed from Unix work
fine.
I ran a bunch of different tests using on both my 850dp and dx printers.
The important thing to recognize is the the 850 printers return data to
the spooler. If the data gets read, then everything works. Otherwise,
the printers dumps a postscript error. This is something I've not
encountered on my Phaser 350/360/550s. The data the printer is sending
by is postscript such as "%%Trailer.." and "%%Page.." commands.
I thought I had found the combination that worked by having ifhp read
"status". Normally, I turn it off (status@). This worked great on my
850dp, but failed on my 850dx!!! (Different Phaser share firmware
maybe?)
Your "shutdown_appsocket" flag works for both 850dp/850dx. It forces
the connection to stay open until the printer dumps its data and FINs.
For now, I will probably use the ifhp-3.3.19 release until 3.4.1 is
ready for prime time. I think I can specify the 3.4.1 ifhp (and config)
for only the 850s.
The traces follow. Thanks again Patrick for the great support.
Test #1 PC->850dp using Appsocket. Works. One page output.
(Note: Two(2) data packets sent from printer.
