Quoth Warren Block on Tuesday, 24 August 2010:
It appears that PPDs are stored in the reasonably-named
/usr/local/etc/cups/ppd. There's a PPD for the LJ4050 in
print/foomatic-db...
And it has
*ImageableArea Letter/Letter: "12.24 12.06 599.76 780.06"
12-point margins on that printer sound about right.
Mine had 18 and 36 for the first two (for an OfficeJet 7310). I tried
doubling them but that didn't seem to make a difference. Did I need to
restart something to get that to take effect?
I suspect those correspond to the margin settings in GtkLP, but fiddling
with those settings has zero observable effect on printing.
Applications should be able to get those values from the PPD.
The PDF in question has a top margin of 18 points, a bottom margin of 21
points, and a printed area height and width of about 576 and 755. It
fits within the printable area of most lasers, and prints fine on my
LJ4250. The bottom will be cut off on a lot of inkjets due to their
paper feed.
For another test, use pdf2ps and feed the PS output directly to the
printer, bypassing CUPS. If the LJ4050N Ethernet is connected (and it
really should be), you can use nc something like this (untested):
# pdf2ps test.pdf - | nc lj4050hostname 9100
If that has cut off margins, it's a setting within the printer.
If it prints fine, it's CUPS.
