Managed to break a nice 6 row epson printhead as I was trying to unclog it. Found a few HP printers which are well under way to being fooled into printing on to flat surfaces. I have to print sequence worked out and is in the process of replacing encoders and switches with a uC. I'm not able to remove the scanner head as it stops the printer from working. So untill there is more time there is just a stray scanner attached to the printer. The good thing about cheap HP printers are that they use minimal sensors making it much easier to fool. Currently I only have 3 pins I have to emulate and a motor drive input.
