Bug#655106: [hpijs-ppds] margins for F4280 are wrong - calling make-duplex-page-sizes-default.sh

[Till Kamppeter <till.kamppeter@gmail.com>]

Originally, the simple paper size names "A4", "Letter", ... referred to
paper sizes with smaller margins/a larger printable area, but these
sizes do not allow Duplex printing, jobs simply came out one-sided.
Office applications only used the simple names for paper sizes as part
of the document (not of the print settings). Trying to print these
documents always gave one-sided output. To really get duplex output on
HP inkjets one had to switch to special duplex page sizes (like
A4.duplex), which once required extra user action and second, was not
possible from many applications (like OpenOffice/LibreOffice). So I made
the script to modify the PPD generator so that the default page sizes
are the duplex ones and the former default page sizes get special page
sizes for small margins (A4.SM).

This way more user's requirements are addressed, as more need duplex
printing and not so many printing of graphical elements close to the
borders.

If you need the smaller margins and do not need double-sided for a
certain print job, simple select the small-margin (SM) page size
manually (or even a borderless page size if available).

It would be indeed a bug if this change is applied to printer which
under no circumstances is able to print duplex (no duplex unit built-in
or as accessory).
