-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Did the printer show up when you wirelessly added it in CUPS, or did you manually add it using the known IP? Maybe CUPS doesn't see it. Wiki page here: https://wiki.ubuntu.com/DebuggingPrintingProblems Relevant part of wiki: Open a terminal/console and run the commands: $ ping <IP of the printer> $ nmap <IP of the printer> Replace "<IP of the printer>" by the printer's IP address. The first command checks whether you can access the printer through the network, the second shows which port numbers are used by the printer and through this which protocols are active (80: Has web interface, 139: SMB, 443: encrypted IPP or encrypted web interface, 515: LPD, 631: IPP, 9100: JetDirect/AppSocket). Install the "nmap" package if needed. Run the commands: $ /usr/lib/cups/backend/snmp $ sudo /usr/lib/cups/backend/dnssd The output shows whether the printers get found by CUPS or system-config-printer and with which device URIs and protocols. Run the command $ /usr/lib/cups/backend/snmp <IP of the printer> if a printer does not get found by the simple "/usr/lib/cups/backend/snmp" call. Find out if your printer gets detected by CUPS: $ lpinfo -v - -------- Original Message -------- From: Stephen <stephen-d@rogers.com> Sent: May 27, 2016 11:44:08 AM EDT To: GTALUG Talk <talk@gtalug.org> Subject: [GTALUG] Printing Problem - Can't find printer I am using Ubuntu 14.04 Printer is Epson WF-2630 Wi-fi connection. Hard coded IP address When I try to print, I get a Gnome pop-up saying printer is off-line. Using the web interface to CUPS the reported error is printer not found. I can always ping the printer. I can always print from a windows computer on the same network. I can, from the CUPS web interface "modify" the printer settings. I click through without changing anything. When I am finished, the stalled print job is printed. Any ideas how I can print without "modifying" the printer settings? - -- Stephen - --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk -----BEGIN PGP SIGNATURE----- iQI5BAEBCgAjHBxBbGxhbiBaaGFuZyA8YWxsYW5AYXppYy5jYT4FAldIcgQACgkQ lQhQ+uFN8kP/zA/9EqwAF2pX/x3oBckpLF+nA8F8vfpAFPjEnK0JVZBzKTwmPE2p DkMfxm+zfVUh5AiJbQ92BSeaY00Xu6hOPhvt8Quj90BKy8411ydI2OiJ3LCwKjcr vWyFF8vbMf5PBWMgcwe55zmY5s3kAQ/DFBJ+QdXAjCugzGKrfJA/8f0MJQ9ZhR+L K+OYqWUPykFDfM7DasF5sBBpw50sg6fwL7CwC6OrOgZ3zFW1SpR9w8NpmRxXvNfZ GiSTFGSuN9tEShnRHcNdt7JQRj7p9Jx4906RAchPwcVeoexnGldkRq38RibteQ2L M20RVym/MmOjMyjAz9sSO4PYz4YHTOID1z3mRbIMWxaEkXF+f9LvWfhT5AMqEA1v 2Nk9oxukey0AkTFH+aeIFNHLsEuuLNLjF8z211BjYa6oc59x8WoQ86mf7ii6FQB+ oqYy3d83aCnPZONNM7RpxDnriov1sTI2WCEebLyuxtdiMX0Agmb3lapwvh/Yp0Kn KBXeUSdp+DK1eDKfDQnewmb/leQx5Um3TH7tgMtrxWO3OkyM2LjInKC1/Q77W3ke 3r+fK1+olsqhJnabz3/3WHxRSsVgDyu/Vw6GtnvUs85keiCfXq4yYyCrlw6C67+c BqVCez7/kPNu8tw1xWjc3YG1qFl2zGQL3vT/TO2noNSwdpf8G5IRMMQAWzY= =eHOR -----END PGP SIGNATURE-----
