I started having exactly this problem when I moved the connection to the
printer to be direct through my computer (connected via USB), instead of
via the network to another older computer (where it was connected via
USB).  Up until then it printed flawlessly, after connecting it directly
I basically have to power cycle between each print. The newer computer
is running Ubuntu 14.04.

I have noticed that when I print something and the print panel appears
and offers me the choice of printers, next to the printer it says
"Sending data to printer" when it's sending the data, and it stays like
that even after the job is finished. If I then print anything, I get
garbage.

I tried unplugging the USB and re-plugging: the "Sending data to
printer" message vanished. I then printed a tiny email message: the
printer showed it was receiving USB data for a minute or two (weird, for
a 10 line text email message!), but did print it correctly. But
afterwards, the print panel showed  the "Sending data to printer"
message, and again the next print appeared as garbage.

The old Ubuntu system had CUPS 1.3.7, the new has CUPS 1.7.2. On the old
Ubuntu system, I installed the .PPD file from Lexmark; when I configured
it on the new system, it auto-detected the model correctly as a Lexmark
c543 (it's a c543dn).

I tried installing the same PPD file as I used on the old Ubuntu system
(8.04.), and re-did the tests, but the situation was unchanged.

It seems a completely reliable indicator of whether the next job will
fail or not is if the print pane says  "Sending data to printer" even
after the job is complete.  At that point, unplugging/replugging or
power cycling is needed.

I'm pretty sure I had no problems printing from the old Ubuntu even
though on that system of course the printer was connected locally, not
via the network.

I hope this information is useful in developing a good fix for it.  It
does sound to me like it's a problem with a later Linux USB system.

Bug description:
  please also refer to this bug - this seems to be exactly my issue and does not seem to be solved.

  ProblemType: Bug
  DistroRelease: Ubuntu 11.10 - all updates as of today applied.

  I followed https://wiki.ubuntu.com/DebuggingPrintingProblems according
  to https://bugs.launchpad.net/ubuntu/+source/foomatic-
  db/+bug/855412/comments/20

  I printed two copies of the same document, since this forces the error
  easily.

  The content under /var/spool/cups/d... look fine - see attached files.

  after cupsenable <PRINTER> the first copy comes out fine - the second
  as random character - I stopped after some pages.

  The test is with Samsung ML-2250 Series (SPL II) - which worked fine under all previous versions of Ubuntu
  Samsung ML-2250 Foomatic/pxlmono (recommended) generates basically the same result.
