Hi! Please remove and reinstall only the affected printer from Settings > Bluetooth & devices > Printers & scanners > Remove, then add it again using Add device.
Since this started after adding a second printer, first make sure Windows is not sending the job to the wrong printer.
- Go to Settings > Bluetooth & devices > Printers & scanners.
- Select the printer you want to use and click Set as default. If you do not see that option, turn off Let Windows manage my default printer first.
