[Samba] Page_log with number of pages prtinted wrong

[Michel Mera]

The Adobe drivers (on request of the printer PPD associated with them) often put a
PJL header in front of the main PostScript part of the print file. Thus, the printfile
starts with <1B >%-12345X or <escape>%-12345X instead of %!PS). This leads to
the CUPS daemon auto-typing the incoming file as a print-ready file, not initiating
a pass through the pstops filter (to speak more technically, it is not regarded as
the generic MIME-type application/postscript, but as the more special MIME type
application/cups.vnd-postscript), which therefore also leads to the page accounting in
/var/log/cups/page log not receiving the exact number of pages; instead the dummy
page number of ‘1’ is logged in a standard setup).
