You won't be printing *anything* until you manually run cupsenable (or do the equivalent using CUPS's web UI). Tim: ha ha ha ha ha. CUPS on my Debian server has been doing this trick for years, I even had to write a cron script to periodically run cupsenable when it noticed stuck jobs in the queue. Now that machine is replaced by a Ubuntu server, and CUPS is still occasionally acting up. (Although, to be fair, the last time this happened it *was* a DHCP issue, and kicking the printer fixed that.)

With a friend we tried an identical printer, checked the ram in the printer before swapping the JetDirect cards (both HP4250s). Both printers then worked... We swapped them back and the problem reoccurred. Also do you have a hard disk in your network printer? Could be worth making sure it's ok...

A quick fix is to power cycle the printer. I don't think this is a HP issue because I don't have this problem with Windows. I don't remember this being an issue under Ubutnu 8.10.

I guess that if it was that simple the problem would also affect Windows and OSX, but perhaps they're using vendor-supplied drivers that identify the printer on the network by name or ID rather than just by IP address.

one thing i can think of is a change on the firewall configuration of the ubuntu PCs… i had this problem in the past, used to use cups quite successfully – until i installed firestarter on the print server. (you can manually open the required ports, 631 IIRC)
