Comment 16 for bug 1377177

I don`t see any 'manual printing mode' at localhost:631 via cups. There is just print quality(draft/normal/high, color/monochrom), page size: A4, media source: printer default, double side printing: off; printed via printing a 'test page'.
High quality gray scale yields exactly the same result: Error Position 77.

printing a self-test instead of a test page yields the following:
%!
  userdict dup(\004)cvn{}put (\004\004)cvn{}put

%%%% If you can read this, you are using the wrong driver for your printer. %%
