[cups] force CUPS print server to fit-to-page

[Josh]

Till,

After your command I see an option is added to printers.conf. But no
changes in output print size. Still 4x6 image.

Not sure if helpful but
lpoptions -l
shows, among other things:

PageSize/Media Size: *Letter
StpiShrinkOutput/Shrink Page If Necessary to Fit Borders: Shrink Crop
*Expand

My understanding that the above is coming from the .ppd file only.

CUPS log file mentions requested page size w288h432 and *Expand to *Letter
is clearly ignored unless it means something else.

Josh.
