The Print Manager uses the calls PrOpenDoc and PrCloseDoc as a signal that a
print job is beginning and ending.  Some applications call PrOpenDoc and
PrCloseDoc on each *page*, rather than further distinguishing pages within
a job with PrOpenPage and PrClosePage, to improve memory performance when
printing with an ImageWriter.

The LaserWriter driver can't know this and happily creates a different file for
every print job it gets.  I've not seen the "data can't be printed" error so
I can't really tell you who to blame for that.
