============================================
There are "problems" with the paper roll ...
(1st)
If you touch it on the backside of the desk: The roll fall out.
(2nd)
The 2_1/4 wide roll doesn't cover the 14th print position, because of
the paper roll fixture.

I made CLIPS out of steel wire to fix the paper roll axle - and
I put 2 WASHERS on the right side of the paper roll fixture.
