Hmm. That is almost NEVER a paper problem, so forget about that.
It is always difficult to diagnose head problems without seeing the machine.
It can be a dirty thermal head, but that's not common unless something has been spilled on it. If you want to try cleaning the head, open the printer, and find the head. It is usually a small aluminium block that clamps against the paper when the printer is closed. it will always sit against the front of the paper. On that block, you will see tiny lines all very close together. They go to a connector at one end, and a thin black line at the top of the head. Wipe this black line firmly with a dry cotton bud.

Here is a picture of a thermal head:

Just above the light brown strip, you can just see the black line. This is what you would rub clean.

Otherwise, make sure the paper is clamping hard against the head while closed. If the clamp is not pressing with the same force at both ends of the head, then you will miss some printing. Try pressing against the back of the paper at the head while it prints, and see if it prints any more than before, then you know if your'e on the right track.


Hope this helps.

Mark.
