I have attached the print driver I got from Zebra for their TTP2030 printer. This works like a windows print driver. You can go into wordpad and do file/print. The OS will normally pop up a print dialog when you try to print this way, but there are ways to get around that in a thick app. I'm not sure about a web app. I also have a customer using the RS232 version of this printer (TTP2010) with our USB to RS232 cable. Their app talks directly to the printer though, no driver involved. I also know of a customer testing successfully with an Epson POS style USB printer that prints post-it style labels. He got an ARM driver from Epson for that, but it just allows him to pass text commands to the printer, it's not a full windows driver. As far as I know, we don't officially support any of these, but I've seen them working.
