p910nd is a small printer daemon intended for diskless platforms that does not spool to disk but passes the job directly to the printer. Normally a lpr daemon on a spooling host connects to it with a TCP connection on port 910n (where n=0, 1, or 2 for lp0, 1 and 2 respectively). p910nd is particularly useful for diskless platforms. Common Unix Printing System (CUPS) supports this protocol, it's called the AppSocket protocol and has the scheme
Windows and Mac Os X (via CUPS) also supports this protocol.
In this guide I show you how to enable printing support for HP M1120 and Canon MP480 printer.
root@LEDE:~# opkg update
root@LEDE:~# opkg install kmod-usb-printer
root@LEDE:~# opkg install p910nd luci-app-p910nd
root@LEDE:~# ls /dev/usb/lp* /dev/usb/lp0
You should also open a port in the firewall for each printer configured. Once the above is done, it might be necessary to restart the print server with:
First, install drivers for your printer.
First, try configure your printer via System Preferences:
This method has worked for me with a HP M1120 printer, but it failed with my Canon MP480 (Error: unable to communicate with printer). So I added manually.
