Have tried the codes you provided, though it would not allow me to enter the <> so left a space instead. Also tried 27,112,0,25,250 which i got from
http://keyhut.com/popopen.htm ( no commas or chevrons as they would not enter ). However, with this code the send command box in the printer properties would not accept the code. On clicking apply it just added some digits I expect to conform with formatting code.
I would rather not use the Generic Text Only driver, as I wish to keep my logo printing.
I will take my printer to my local POS hardware shop to test there.
