I am running into a simular problem with my ip connected printers.
I have tried to disable and enable the que and it has had no effect.
Couple observations:
Only seems to happend to ip printers on site, not those connected through the vpn at physically different locals.
I can go into the print que and delete the next job in line after the line denoteing that is is sending the jobs to the specified printer and it will then print the next job after the one deleted, but then hangs again. So delete one get one is the result. Normal printing dose not resume until the que has been emptied either in this mannor or by removing all jobs (EXCEPT the line denoting where it is sending them, it removes itself after all jobs are gone).
I am presently testing the response time delay to see if this will clear it up. However the problem is erractic and unpredicable. So the fact that it hasn't reocurred yet really doen't mean anything until I am no longer plagued by these jams.
jamyn have you any success in tracking down this issue?
