Okay. FWIW LPI had never effected the scaling of X but Y. if
you were confused or just a typo.

As you may know there are no ways to specify a font nor a
font size in texttops or a program that works like a CUPS
filter. so CPI/LPI just works to scale characters, in other
words to specify the font size. that's why I may maintain it
in the cups filter patch so that it's required for CUPS
filter, but may not be for paps itself.  I don't know which
ways are correct, because it totally depends on its
architecture -- texttops may wants to be added such options
but presumably it may be supposed to be PostScript-compliant
font name and the font size since they deal with PostScript
as the basis of their architecture.  I don't think that is a
good idea, particularly to print the text out, which
requires CMap support to get it working properly.  people
who wants to print something out with CUPS should just print
it out. IMHO the obvious options like --lines-per-page,
--chars-per-line (which is referring from a2ps's) and
CPI/LPI should be helpful rather than just a font size
because they don't want to fail the printing with the unsure
font size, how it looks like.

However specifying a font and a font size may be still good
feature for paps since paps doesn't support the direct
printing or just works as a frontend filter program, because
it won't causes wasting their papers directly. they can just
try out before getting the real printing.  but CUPS filters
aren't supposed to do so since it has to be a backend filter
program.

Sounds nice. so does people need to give paps a Pango marked
up text, right? it would be nice if paps can highlight the
text automatically according to its format.
