Fix for slow print preview

[Howard Goldstein]

A few minor releases ago OO and LO both added a little thumbnail preview
to the printer dialog.  For those with network printers and using old
but seemingly correct printer drivers these newer releases caused the
print dialog to stall for a few second while the thumbnail was drawn up
somewhere.  Everything else continued to work fine but the printing
dialog was terribly annoying.

I never did find precisely where the somewhere was (the X process was
eating up 100% of the cpu during this thumbnail draw) but the fix for me
was to change cups and the lo printer driver to the the ones marked with
"-ijs".  In my situation the old driver was an ordinary laserjet4
attached to cups with the recommended HP .ppd from HP.  *These old
drivers are not IJS compliant and that results in the long delays*

To work around the problem therefore replace your cups and LO printer
driver with a newer driver support this IJS standard which appears to be
some .pdf like standard.  The churning in X was probably some bit
converting the postscript to a .pdf thumbnail for the print preview.
The preview should occur instantly with an -ijs driver.

Not to forget a huge *thank you* to our freebsd-office team for the hard
work pays off and freebsd 9 is deployed on a law office desktop here
because it just works.
