Hope the switchover to PDF will eliminate this problem or at least make
at least bad print data from applications occur less often.

These are important points which we should discuss on the printing summit.
I suggest the following for the apps:
- On the editing screen of a document-producing application there should
be a fine gray frame to mark the imageable area of the currently chosen
- There should be a print integrity check, which tells the user whether
there are graphical elements in the document which are beyond the
imageable area of the current printer, whether there are pages with a
paper size not available on the printer, colored elements when a bw
printer is chosen, embedded images with way to low resolution, ... and
an easy way to quickly jump to the offending element, Craig, you have
chosen me such a feature in Scribus in Luxembourg.
- The printer's resolution should be read out from the print
queue/PPD/CUPS and images pre-rendered in a resolution compatible to the
- There should be a bw-view button, so that one can quickly switch the
screen view of the document to bw ore grayscale, to visualize problems
which can occur when faxing or printing in black and white.
