Re: [gentoo-user] CUPS remote printing drives me crazy
Many thanks to all who helped me. For cupsd.conf on the server machine It turned out that I needed Listen localhost:631 in addition to Port 631 Listen /run/cups/cups.sock Furthermore, on the client machine I had typo DeviceURI ipp:://MyServer/printers/duploc_usb (note the double colon) Unfortunately, CUPS doesn't seem to check the syntax of DeviceURI or it doesn't report this. One simply gets "printer could not be located" when one tries to use it. I didn't want to use enter the SERVER name into /etc/cups/client.conf on the client machine, since I want "double spooling', i.e. the client machine should accept the print job even if the SERVER machine is down. --- Yes, I still have an old printer which only has a USB-connection and an Ethernet connection. Unfortunately, the Ethernet connection broke down recently. I don't think that WiFi is the best solution since - at least me - have only 60 Mbits/seccon on the WiFi but 1 Gbits/second on the wired Ethernet - and some files to be printed are quite large. Thanks again, Helmut.

Re: [gentoo-user] CUPS remote printing drives me crazy
Hello! I could not connect through the cups web interface.

Depends on how much you have to print and how often. For these few pages I print every now and then it doesn't matter. Wifi is fast enough for those cases. Heiko

Does this printer have Wifi support? Then it would be a lot easier. If you would disconnect this printer from the one PC and connect it to your network over Wifi then you probably would only need to configure your firewall. The printer would then be found automatically by CUPS. Heiko

Set the server in cupsd.conf to be listening for connections on the IP address which will be used by the client. The default is to only listen to connections from localhost. 2. As Neil suggested make sure you allow PC(s) from your LAN subnet to access the cups server. 3. Check your firewall on the server allows connections over the corresponding protocol (port 631). 4. Use telnet/netcat/nmap to see if the client can access an open port 631 on the server. This should get you talking to the server. Should you still have problems printing, you can thereafter troubleshoot it in more detail by checking the server's cupsd logs. Beyond simple printing you can allow access to the server's admin pages, logs and what have your from the client, but you may not wish to do this for security reasons. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
