[cups] Text being garbled - Ricoh Pro 1156/1157 - Cups 1.5 and 1.7.2

[Chris Coleman]

Hi all,
I have been using Cups for quite some time now with stellar results.
However about 6 months ago an error was found in a printed document in
which a few discrete pieces of text had been garbled. Nothing odd about the
text in question. I believe it's an Arial Bold 8pt or 9pt table header
element.

The document being printed was actually a large collection of smaller pdf
files that had been merged together. I was able to go back to the original
2 pg pdf and reliably reproduce the issue by simply printing it through
Cups. However, if I were to open the file on a windows machine and print,
it would print without error.

At the time, we were running on Ubuntu 14.04 with Cups 1.7.2. I had a
backup server that was running ubuntu 12.04 and cups 1.5.3 so I switched
over to that and the issue went away. Woohoo! So we moved our workload over
to that server.

Fast forward a month and boohoo! the problem appeared again on the 1.5.3
box. Different files of course. And once again, printing from windows was
fine. At that point I decided to go ahead and put together a fresh ubuntu
12.04 installation without any updates, the problem persists.

Unfortunately I can't really share the documents in question... I would be
quite grateful if anyone could provide me with any troubleshooting
advice/ideas that I could use to pursue this?

Thanks,
Chris
