I have about 6 in good shape EPSON Tm88III thermal printers. According to the odoo page, TM88 is one of the supported printers, however since this is a serial only printer and, so it is not serial over usb, I bought LogiLink serial to usb converters, but have hard time to get printers recognized.
What I managed to do for now is change the IN and OUT addresses for serial communication so because LogiLink advertises 0x083 and not 0x081 which is set as default in printer module. So after changing default addresses to the ones that Converter is actually using I can get posbox web interface saying that printer is connected (it finds Prolific instead of EPSON but this is due to vendor of the cable converter).
Anyhow, there is no printing happening, and whenever I send something from the pos, I get Operation times out error (110).
Anybody has any clues or suggestions? I have GBP 1000 value of printers on stock that are almost unused so far and I would hate not to reuse them.
I am using this converter:
I also have an SAM4S printer that has USB connection, but that one I cannot even get connected.
