Aha! Something doesn't like that URI, I changed the selection in system-config-printer to use "usb #1" and the DeviceURI changed to usb://HP/LaserJet%202300%20series and it's all happy now. I use CUPS itself to configure printing (that works the same on Debian, RHEL-clone and anything else I use). I have this, for a different model of printer, and it works: DeviceURI hp:/usb/HP_LaserJet_3052?serial=00CNCK315110 _I_ am using CUPS 1.3.0 and hp* 1.6.7 (I need the newer support) on Nahant-clone in this case. -- Cheers John -- spambait 1aaaaaaa-M5lLXDFvHK1J+1enrU1vWw@xxxxxxxxxxxxxxxx Z1aaaaaaa-M5lLXDFvHK1J+1enrU1vWw@xxxxxxxxxxxxxxxx Please do not reply off-list

Re: persistent static routes

Based on looking over /etc/sysconfig/network-scripts/ifup-routes, RH5 will look for the routes in route-ethX and will cope with the GATEWAY<n>, NETMASK<n>, ADDRESS<n> format as well as the second format. In looking at the same script on RH3 and RH4, they all reference the GATEWAY<n>, ... as the "new format" You can always use system-config-network to see what RH creates for you when using their tools.

Printing problems -- "open print channel failed; will retry in 30 seconds..."

Hello All, I've got an HP laserjet 2300 which is plugged into the usb port on my RHEL5 server so it shows up as DeviceURI hp:/usb/hp_LaserJet_2300_series?serial=CNCFF60878 in /etc/cups/printers.conf. It refuses to print though. The cups status page always shows "open print channel failed; will retry in 30 seconds..." unless I disconnect the printer in which case it shows that it's not connected. I can't see anything vaguely relevant the cups log files, I've tried disconnecting and reconnecting, I've tried power cycling the printer, I've rebooted the server and nothing makes any difference except that I can get the printer to admit it's not connected (googling seemed to suggest that power cycling the printer would do the trick, but all I found apart from that was sympathy for the problem). Has anyone else seen something like this and, more to the point, does anyone know how to fix it? jch
