Incorrect Display Content Formatting

If the customer display shows garbled or misaligned text, the issue may stem from an incorrect command set configuration. Always double-check that your POS system is using the correct command set for the display model (e.g., EPSON, LOGIC UTC, DSP800, etc.).

• Mismatched command sets can cause unreadable content, incorrect formatting, or missing display updates.
• Review your software settings and documentation to ensure compatibility.
• If applicable, send a test command manually and verify the response format.
