/* This piece of PostScript code (initial idea 2001 by Michael
41
Allerhand (michael.allerhand at ed dot ac dot uk, vastly
42
improved by Till Kamppeter in 2002) lets Ghostscript output
43
the page accounting information which CUPS needs on standard
45
Redesign by Helge Blischke (2004-11-17):
46
- As the PostScript job itself may define BeginPage and/or EndPage
47
procedures, or the alternate pstops filter may have inserted
48
such procedures, we make sure that the accounting routine
49
will safely coexist with those. To achieve this, we force
50
- the accountint stuff to be inserted at the very end of the
51
PostScript job's setup section,
52
- the accounting stuff just using the return value of the
53
existing EndPage procedure, if any (and providing a default one
55
- As PostScript jobs may contain calls to setpagedevice "between"
56
pages, e.g. to change media type, do in-job stapling, etc.,
57
we cannot rely on the "showpage count since last pagedevice
58
activation" but instead count the physical pages by ourselves
59
(in a global dictionary).
