I’m having recurring problems with our print server, which is running CUPS (cups-1.1.19-13) and Samba (3.0.7-2.FC1) on a 2.4.22-1.2194.nptl kernel. All of the office printers are set up with all services disabled except for LPD, and CUPS is set to print through LPD (ex. lpd://hp4050/raw) with all formatting done on user’s Windows machines (all running XP). For the most part it works fine with our main HP Laserjet 4050, but I have recurring problems with another couple of printers, an HP Laserjet 2300 and 4200. When I go to add a printer in XP for either of these printers, right after I select the PCL driver to install locally, the Add Printer dialog freezes. Then I see a bunch of hits on the firewall from the XP machine to the server on port 135, which I’ve blocked (and I don’t think is necessary for CUPS, or am I wrong? I’ve tried temporarily opening the port but the problem persists). Then SpoolSV.exe on the XP machine starts climbing to around 60/70% CPU use on the XP machine and subsequently one of the smbd processes on the Print Server starts climbing to a similarly high CPU usage. The only solution is to force quit the Add Printer dialog, and remove the printer, at which point both SpoolSV and Samba go back to their normal CPU usage.<o:p></o:p> <o:p> </o:p> Has anyone seen this problem, and have any idea how to fix it? Any help would be much appreciated!
