At least for the PRINTER device in IDL you can (in IDL 5.1.1
and higher) get the pixel resolution of the default printer
with the GET_PAGE_SIZE keyword to the DEVICE command:
Set_Plot, 'PRINTER'
DEVICE, GET_PAGE_SIZE=thisPage
Print, thisPage
Presumably with this information you can perform the
same tedious tasks you are now performing for the display
device.
I agree it would be nice to have this functionality built
into IDL.
Cheers,
David
