TROUBLESHOOTING THE M204: Windows Problems

Printer and Network Errors

Anytime you have several Windows for Workgroups (WfW) stations printing
directly to a print server, you may run into various printer and network errors. The
problem occurs when one station is sending a print job to the printer and another
station tries to send a print job to the same printer at the same time. The print
server tells the second station to hold on to its data until it has finished with the
first job. However, the Print Manager on this second station doesn’t like this and
errors out. This requires that the user on the second station resubmit their job
when the printer is clear again.

This problem will occur with any external print server that does not spool entire
print jobs (which is the case for every print server on the market today). The Print
Manager likes to send the data it spools immediately and if it can’t do this
(because the printer is already busy with another job) it will produce an error say-
ing the network or printer is busy.

The best solution to this problem is to then have a central spooling station (like an
NT server) which allows each WfW station to spool the print job immediately to
the server’s hard drive. The NT server then can sit with the print job until the print
server/printer can take it. The print server then only deals with one station and it
goes through each job as it gets queued up.

It is not possible to set up a WfW station as the central spooling device since you
cannot share a printer on the network that is already being shared. It is because a
“net use” connection is used between this central station and the print server that
causes the problem. However, a central NT station can offer a shared network
printer to these WfW stations.
