With a little bit of luck you can print dot codes on a (nowadays) standard
inkjet printer. The "lowest" I could go on my printer for an acceptable
result was 600 DPI and high quality inkjet paper. For best results, use 1200
DPI and photo paper. Make sure the dot code is printed using my tool at the
correct size, which is a little bit larger than a real dot code. The dot
code will be printed at the bottom of the page, ready to be swiped through
the e-reader.

So far working results have been produced on a HP DeskJet 3650 and an Epson
Stylus C85.
