Well I just looked at the 'owners manual' for the NCR thermal printer I typically encounter, which just happens to do what you asked about for the Epson. It's an eyeopener for a hardware guy. You can upload multiple 576x512 pixel bitmaps into either ram or nvam, provided you don't go crazy & try and upload a single 2 Meg bitmap on a 512k printer.
It's just the software control codes to do all a that...well let's just say if I was configuring one of these from scratch I'd be looking for a nice friendly GUI application to help me.
