FAQ# 2290: My Serial printer isn't printing with Aloha POS or it's constantly printing question marks or symbols.

Question

My Serial printer isn't printing with Aloha POS or it's constantly printing question marks or symbols.

Answer

Aloha POS requires your serial printer to have a specific serial setting:

  • Baud Rate: 9600
  • Data bits: 8
  • Parity: Even
  • Stop bits: 1
  • Flow Control: Xon/Xoff
The way of setting this on your printer may vary, but it is usually by toggling the physical DIP switches located on your printer.
