Hi Gus, The limitation is going to be more than firmware, but mechanical. The motor only has so much resolution if it's a stepper, and if it uses encoders (which it does I believe, on the 3000 for the paper advance at least), your resolution is that of the encoder, period. Firmware or special commands can't override the mechanicals! From what I understand, the only way to get 1440 is using "micro weave". If you want a copy of the ESC/P command set, you can get it from the Epson developers site...but that's not all there is, as apparently there are more undocumented commands, unless you're on NDA with Epson...but still, those commands can't override the mechanical limits of the printer.
