About the cut: I have never tried this. Theoretically, this should work by specifying a "sheet size" with a length of just 8mm. But then there is almost no space left for printing, as a 5mm margin is specified.
My printer often stands around unused for months. At most, a print head cleaning was necessary. As the ink cartridges are located directly above the
and "travel" with the print head, very little ink is lost. There are no "ink hoses" due to the short path, so they cannot become blocked.
