Repair work on the mechanics of the thermal printer HP-82143A

[rprosperi]

To try to nail it down, please try to upload a relatively small PDF file and see if that works. Even though your overall account may have enough available space, possibly that file is too large for a file size limit (which I don't know the max size).

If the small file works, then maybe you could try to split your large, single file into 2 or more smalller PDF files.
