I've never really thought of that too much. It's probably possible considering when I've done some field maintenance on a IBM receipt printer in the self-diagnostic tests it was mentioning info on what was in memory and it had a image in there. An image I think came out during a self-test and the attached pos was down. I probably know someone that would know for sure and if he does he's probably got a program to do it - he sells & maintains POS units.
Most of the time the units I work on, I think just send the required image to the printer when it's deemed needed.
As for a networked thermal printer, I know some have a Ethernet port I've yet to see it be used it's mostly been just some form of serial(USB, RS-232, IBM's oddness) or parallel.
Here's a curly tech question, has anyone come across a stand-alone MS Office-compatible database-like application that I can use in a Motorola/Symbol MC70 - yes I do own a 2nd hand one, no I haven't enabled the GSM phone yet and I've still to acquire a wifi module for it. I know what I'd like it to be like -filemaker pro or MS works DB form page- but I doubt it would be a simple as that due to the output needing to go into certain fields of a excel worksheet. Which I can do now manually with it but it's fiddly.
