Install Epson AL-M1200 printer on Ubuntu

Ubuntu seems to have trouble talking to the Epson AL-M1200 printer. These instructions will get it working. Based on a set of instructions found here.

  1. Download epsoneplijs-0.4.1.tgz -file from here
  2. cd Downloads (or whatever directory you downloaded the file to)
  3. tar zxvf epsoneplijs-0.4.1.tgz
  4. cd epsoneplijs-0.4.1
  5. ./configure --prefix=/usr
  6. sudo make install
  7. Download PPD file from here or here
  8. Connect your printer to your computer and turn it on. (You can do it in the beginning, but at least now you need it connected and powered on.)
