Black Mark test
The printer moves the paper to the next black mark, prints three lines, moves the paper
until the next black mark is underneath the cutter (one Form Feed) and cuts the paper.
After this operation, the paper is moved backwards to the first print position (top of form).
This test is repeated continuously and can be stopped by pushing the Linefeed button
once.
