There is room for improvement in printer support. I have never had trouble installing my Deskjet 4100 in every other Arch distro I have used, i.e. cups, add or find printer, enable, start and off we go. The same procedur in Liya fails everytime. I have tried the ipp/https route also. Still no go. It would be nice if it were handled as in debian/ubuntu based distros, but at the moment the only way I can print is by emailing to my printer.
