Re: 400 printing over a WAN

[Chris Whisonant <Chris.Whisonant@xxxxxxxxxxx>]

No comments, but I have another question.

We have a subsidiary located about 5 miles away on our network. 
They use the 400 for all their data and printing.  However, we have
run into problems lately.  I will try to be brief and list what we
HAVE tried.  We have an IP connection between here and there on
fiber.  There are two things they "must" print from the
400.  The printer is an IBM 4317 with IPDS.  The first job is a
query (only a couple of users do this for their peace of mind) followed
by invoices (the query is not needed for the invoice, the majority ONLY
print invoices.  The invoices go through a form-server to place
headers, logos, and other data in the print file.  Data has to go
from the 400 to the printer, and then the printer sends data back to the
400 to proceed.  A commtrace has revealed that somewhere the printer
is not sending the data back.  Here is what we have done: 
changed ethernet card, recreated PSF config, recreated DEVD.  This
would lead us to believe it's software-related, so we then rerouted the
data to our IS department to a test 4317 with the same
configuration.  The invoices printed fine.  OK, it could be the
printer, so we took a brand-new 4317 to them and brought theirs back to
our department.  Theirs worked up here but the new one did not work
at their location.  OK, so now we looked at communications
problems.  Last week we switched out the CSU/DCU and rebooted their
router.  Guess what?  It worked!  It proceeded to work for
the next week, and Tuesday it reverted back to its old ways again.

Any other guesses?  I may have left something out, so make
suggestions.

Thanks so much,
