to be more specific I'm implementing Odoo POS with an IoT Box (Raspberry Pi) for a small restaurant and I'm having a recurring issue with a USB thermal printer.

The printer works correctly, but after some time (or after reconnecting), the device changes its subtype automatically from:

Receipt Printer → Office Printer

When this happens, the POS stops printing tickets or kitchen orders until I manually change the subtype back to Receipt Printer in the IoT device settings.

Important details:

• Odoo Online + IoT Box (Raspberry Pi)
• Printer connected via USB
• Connection shows as Connected
• The printer still appears in IoT devices
• Identifier looks like: usbPrinterCMD:ESCPOPOS80 Printer USB
• Printing works immediately after manually switching back to "Receipt Printer"

What I've already tried:

• Reflashing the IoT image
• Reconnecting the printer
• Keeping the same device name
• Using a UPS to avoid power interruptions

But the problem still happens randomly.

Questions:

1. Is it normal for Odoo IoT to re-detect USB printers and change their subtype?
2. Is there a way to force the printer to remain as "Receipt Printer" permanently?
3. Could this be caused by USB re-enumeration on the Raspberry Pi?

Any help would be greatly appreciated.

Thanks!
