Issue #3: Prints Gibberish (Diamond Question Marks)

• Cause: The POS software is sending the wrong code page (e.g., PC437 vs UTF-8).
• Fix: Download the "KP206B Setting Tool" (usually on the driver CD). Connect via USB and change the default code page to match your region (e.g., "Windows-1252" for English/Western Europe).

7.5 No Linux USB detection (lsusb shows device but no /dev/usb/lp0)

• Kernel module usblp blacklisted. Run: sudo modprobe usblp. Then sudo chmod 666 /dev/usb/lp*.

Setting Up the Driver for POS Software

Your hardware is useless without software integration. Here is how to select the driver for your POS system:

• Square / Shopify POS (iPad): You cannot use the Windows driver. You must use Bluetooth. Pair the printer via iPad Settings > Bluetooth, then inside Square POS app, select "KP206B-UB" as the receipt printer.
• Toast / Clover: These systems use proprietary drivers. You will likely need to flash the printer with a specific firmware. The generic KP206B-UB driver will not work here.
• Self-hosted POS (Loyverse, Odoo, ERPNext): Select "ESC/POS Printer" from the list, then choose "KP206B-UB" as the device. Enter printer IP if using Ethernet (note: UB is Bluetooth/USB only, so use local USB port mapping).

Part 7: Updating and Uninstalling the Driver

When moving to a new POS system or encountering persistent errors, a clean uninstall is necessary.
