Hello,
there are not that many threads about printing, and information on this topic relating to openwrt/LEDE is scarce. The CUPS printing package is not maintained since years ...
I thought it was a smart idea to have the printer connected to the router and access it from all LAN devices. Doesn't seem to be a popular idea.
I am aware of the kmod-usb-printer kernel module. But, my printer is the Kyocera FS 1010 which does not like to be addressed by the kernel. Some time ago I found this thread giving an explanation. I had to remove the printing module from the kernel configuration to get the printer working (using CUPS on my Linux system, with OSX and Win no problem, unfortunately).
In openwrt/LEDE, kmod-usb-printer seems to be mandatory. Is there no alternative?
Cheers
Lokesh
