Modifying the printer is only part of the problem. Have you tested the ink to see if it is waterproof? If you use water based ink, the etchant will dissolve the ink and you will remove all the copper, not just where desired. Most ink jet printers use water based ink, however solvent based ink is made. IMHO the solvent based ink would plug the nozzles on a water based printer, so it is not simple to switch. I have used India Ink applied by hand with some success, but sometimes it comes off as well.
