This is the best $9.99 I have ever spent. My much used and carefully maintained Epson R1800 stopped working shortly after the dreaded notice appeared 'Service required.......' I had always been careful to soak up the excess ink in the sponge ink reservoir and the printer was still working beautifully. Thank goodness I looked on Google for a solution and it came up with you guys, like the cavalry coming over the hill to rescue me! the reset worked perfectly and my beloved printer is once again up and running. Thank you so much, I can unreservedly recommend your software.

Went to town and bought a cable. Printer status is now restored. Thank you. I\'m not the most computer tech person which added to the confusion. I do suspect there maybe a few others like myself that you could lessen some confussion by including a note that says \"if your printer is connected by wifi it will be necessary to use a USB cable during the hack\". Thank you again for the program. It made me both mad and sick to think that after so little use of this printer that I was going to have to throw it out. Gratefully yours, Dinesh Kumar
