Client set to TCP/IP WAN access. HPLJ4 drivers on server and clients. Could be fine for weeks or hours, i get a call "I cant print!" look in the printers folder and theres jobs sitting there. Stop Spooler service, delete jobs, restert spooler. Temporary fix, been going on a while. Service release 3 claims to address issues like printing to wrong default printer and stuck print jobs...well it didnt. any ideas?
