FAQ# 2290: 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.
