![]() ![]() The Gutenprint printer application should wrap the Gutenprint library and so support all the printers the library supports. The new mode of using this library should be a new Printer Application which will be the student´s task to create. It should be rather easy to add more ways of using the core driver functionality, as this functionality is in a library, all capability information of the supported printers, dithering and color correction algorithms, … It is popular under users of both Linux and Mac OS X.Ĭurrently, it supports printing either the classic CUPS way, by a PPD generator and a filter or by a plug-in for the GIMP. You might even have to upload the printer's cert yourself.Gutenprint is a printer driver for high-quality inkjet printing which is under continuous development for many years already and supports hundreds of printers. ![]() Using ipps instead of ipp complicates things since you now have also make sure that cups trusts the cert Sure the printer is configured to use a static address. I assume you saw the list of servcies/queues when you connected to the printer via a browser at portĦ31 since you used the connection string ' ipps://192.168.11.248/ipp/print'. ![]() I would test by connecting to cups and using Code: You could also add second printer using the Generic or Epson make and then use Code: I see a possible driver from gutenprint (for make Epson): Code:Įpson EPL-7100 - CUPS+Gutenprint v5.3.3 (en) What gives?ĭo you have net-print/gutenprint installed? Might have a driver for your model. So I'm left assuming that it's trying to connect to the cupsd server, but connections to the cupsd server seem to work fine, given that I can access localhost:631 from the browser and manage printers from there. I'm pretty sure "lpinfo -v" is just scanning for services and isn't trying to connect to any particular server. Lpadmin: Unable to connect to server: Success Now, when I try to set up the printer using localhost:631 on the browser, I'm now only getting an option for "EPSON 9-Pin Series" and "EPSON 24-Pin Series", and not the printer I'm actually using (which is an EPSON XP-7100).Īlthough I'm having printer connection problems, my main problem is that the CLI tools for CUPS are all returning that they are "unable to connect to server" or "unable to connect to host". I found the queue name in a Network Services section of the printer's On my brother printer the connection spec for cups is: Quote: , and see what print queues are supported. You might try connecting to the printer address with a browser:Į.g. Get things working w/o zeroconf using just ipp, then try using ipps. If the printer supports ipp, then you might try the IPP Everywhere printer type. The invalid name might have something to do Printer via the ipp protocol (with encryption - ipp s) and can'tįind the invalid dns name. You error message looks like cups is trying to access a network I would expect that connecting to localhost:631 is connecting to the cupsdĭaemon. Here it is:Į Unable to resolve \"ipps://EPSON%20XP-7100%20Series._ipps._tcp.local/|EPSON XP-7100 Series\".Į Unable to create PPD file: Could not poll sufficient capability info from the printer (ipps://EPSON%20XP-7100%20Series._ipps._tcp.local/, ipps://EPSONB46243.local:631/ipp/print) via IPP!Į copy_model: empty PPD fileĮ Returning IPP server-error-internal-error for CUPS-Add-Modify-Printer (ipp://localhost/printers/xp7100) from localhost.Į Unable to queue job for destination "EPSON_XP-7100_Series".Į Files have gone away.Į Unable to resolve \"dnssd://EPSON%20XP-7100%20Series._ipp._tcp.local/?uuid=cfe92100-67c4-11d4-a45f-389d92b46243|EPSON XP-7100 Series\". Perhaps I'm missing a USE flag? Or is there something I need to enable in my kernel configuration? What am I missing here?Īctually, I found an error_log file in /var/log/cups. My USE flags are the flags in the default/linux/amd64/17.1/desktop profile, as well as:Īnacron pulseaudio i3wm network cups zeroconf I've installed CUPS, but whenever I run lpinfo -v to look for printers on my network, I keep getting "lpinfo: Unable to connect to host" as my output.Īccessing localhost:631 on my browser seems to work fine, but whenever I set up a printer and attempt to print something on it, I getting "Unable to locate printer "(printer hostname).local"".
