Preparation
Driver for the printer
There is a documentation for Ubuntu
here.
In Arch it's the same but driver installation is much easier by using the
AUR.
If you have installed it,
aurget can find the necessary package and download it.
aurget -S epson-alc1100-filter
mkdir epson-alc1100-filter
cd epson-alc1100-filter
wget http://aur.archlinux.org/packages/epson-alc1100-filter/epson-alc1100-filter/PKGBUILD
makepkg -s
pacman -U epson-alc1100-filter-1.2-1-x86_64.pkg.tar.gz
Use Printer in cups
sudo pacman -S foomatic-filters
sudo /etc/rc.d/cups restart
