In addition to the other recommendations, I'd suggest using ??? to write to the Pole Display unless it installs as a printer, with a printer driver. ??? writes directly to the device without having Windows try to interpret the data being sent to the port.

You need to end each line with a CR/LF pair ( CHR(13) + CHR(10) ) using this approach. I would suggest sending an End of Page character ( CHR(12) ) followed by a CR/LF pair prior to sending each pair of messages; if may be enough to send the CHR(12); experiment with the Pole Display to find out. There is probably documentation for the Pole Display that describes the control sequences which it can interpret, and that would be the most definitive source.

There is a standard set of controls for handling POS equipment called oPos; I've seen it offered by Epson in the past. Several people on UT have used it - I'd suggest searching the message base for the term oPos to find messages regarding using it with point of sale equipment.
