  Thrilled to bits - I thought my trusty printer was destined for the scrap heap ( although nothing wrong except it would no longer operate due to "ink pad full") and I would have to buy new, until I alighted on your product . Also if the ink pad actually causes problem tyou advise where I can buy a replacement kit and do it myself. You perform a great service to printer users. Well done!

  Thanks for this amazing software! This really helped me in my issue with Epson L200 Printer. More powers to the devs of this software.

  Always concerned that these things don't work but this time - really happy to say the long distance (USA-UK) fix worked perfectly. Thanks and kind regards
