I put AXIOHM into Google and the very first hit was for the web site www.axiohm.com. I went to that site and found there a link to www.tpg-axiohm.com. I clicked there and got to the TPG web site and did some surfing and came to the page -- http://www.tpg-axiohm.com/products/kiosks/a226.asp. On that page there is a link to download a data sheet for the Model A226 printer. It is indeed a thermal printer with a paper spool roller. This one uses paper up to 90 mm wide.

Is this the unit you were looking for? This one is about 103 mm high, 171 mm wide and 203 mm length.
