hp-setup has no option to set media size (A4 versus Letter)

[Johannes Meixner]

I run hplip-3.13.9 RPMs made by the openSUSE build service
on my SUSE Linux Enterprise 11 Service Pack 2 64-bit machine.

I have a HP LaserJet 1020 connected via USB.

When I run "hp-setup -i" or "hp-setup" there is (as far as I see)
no option to specify the media size (A4 versus Letter)
that is actually loaded in the printer.

In my case A4 is loaded in the printer but the print queue
gets set up with default PageSize Letter (output cut here):
=================================================
# lpoptions -p HP_LaserJet_1020 -l
PageSize/Media Size: *Letter A4 Photo ...
PageRegion/Media Size: Letter A4 Photo ...
...
=================================================

As consequence printouts do not fit on paper e.g. via
"echo Hello | a2ps -1 -o- | lp -d HP_LaserJet_1020"
where a2ps produces in my case A4 output by default
of for any application that also produces A4 output.

I need to run "lpadmin -p HP_LaserJet_1020 -o PageSize=A4"
to set it correctly.

I would like to have an obvious option in hp-setup to specify
the default media size that is actually loaded in the printer.
