I remember there being a line of itsy-bitsy printers years ago, so I looked in my DigiKey catalog (paper catalog), and sure enough, they're still made.
Not sure if this is what you're looking for: check out the EPL1902SC printer module. Pretty cheap (<$30), although you do need to buy an interface board for it which is not cheap ($147).
That is very true. What is the interface for ? Perhaps to be driven from an OS such as Windows? All I need obviously is to send ASCII data to the printer and let it "do its thing"
It might be more complicated than that. I'm guessing the IF board has ROM for character generation, and that the printer module is driven at a pretty low level (select which pins to fire, carriage motion, etc.). A bit of work to come up with a workable printer, but perhaps doable? I really don't know, but maybe worth checking into.
Nope, no graphics required, just pure and simple ASCII characters. Although the PC16F688 is a GR8 device for its UART I am using the new PIC18F26K80 with a 12-bit A2D for another function. The problem is that there is no 230Vac mains available at the site where the POS is going to be used, hence the requirement for a +12Vdc, or whatever, printer module. I would have thought that this would be an easy find
