Problems solved by technology

In the printing unit with this structure, the problem of the inconvenient installation of the medium in the printing unit with the integral structure of the cutter is solved, but a new problem is brought: sometimes, due to some reasons, the cutter is damaged. The movable blade 18 is not retracted, but is pressed on the static blade 12, so that the upper support 11 cannot be opened, causing the failure of the printing unit
