Hi,
I am a POS developer based in Australia.
I have a lot of experience wiht Epson POS printers, and the ESC/POS command codes.
I have existing code to 'kick' a cash drawer from VB and C#.NET that is connected via the RJ11 port.
I am not familiar with the T32-302 printer, in fact i can't find anything online about this printer. Are you sure you have the model number correct?
Look forward to hearing from you,
Caleb.
