Note
When the paper feed button is pressed, the paper will only be transported once the printing of a
line is fully completed. At that time, only one line is fed, followed by a small break. If the button is
still held down, the paper will now be fed steadily line by line, until the button is released. This
feature allows specific feeding of only one line through brief pressing of the button. Afterwards,
the printer continues with normal printing at the start of the next line.
Paper feeding cannot be done for more than a cycle of 5 seconds consecutively because of an
automatic feeding end, if another cycle is requested , release an press again the button.
