Printing is not possible. (USB connection)

I cannot use some buttons or functions in P-touch Editor or the printer driver. (For macOS 10.15.x)

My printed documents are incomplete or a blue screen appears when printing after a Windows 10 update (March 2021)

I connected multiple printers of the same model to one computer but can only print from one of them.

Pages don't print. What should I do?

Paper does not move through the printer even though the motor is running.

Paper moves through the printer, but nothing appears on the paper.
