I find the MacVim can't print the CJK character correctly after
pressing cmd+P. I don't know which file should be modified to work
correctly.
Can MacVim print the line number and change the font size ?
My OS is lion 10.7.4
paps is your friend, more exactly paps|lpr
You can do
paps file.txt | lpr
but I don't really like all the paps defaults so I've
written a wrapper around paps|lpr or paps|ps2pdf which
by default adds a wider left margin, always prints page
headers (to get page numbers), sets a smaller font size
and lets you set font name and font size independently
of each other. It also has an option to pipe paps output
to ps2pdf instead of lpr and create sensible PDF file
names while doing so, an option to pipe paps output to
yet something else, and options to pass raw paps options
or lpr/ps2pdf/whatever options.
Last but not least it has an option to prepend line
numbers to the input, which paps can't do by itself.
It's attached. You can set your own defaults near the top,
and read help for the options with perl printme.pl --help

printme - print text files w/o line numbers through paps and lpr/ps2pdf.
USAGE: printme [OPTIONS] [filenames]
A wrapper around paps|lpr or paps|ps2pdf which
1) adds an option to print line number,
2) by default adds a wider left margin,
3) by default prints page headers (to get page numbers),
4) sets a smaller font size, and
5) lets you set font name and font size independently of each other.
OPTIONS
=======
OPTION ARGUMENT MEANING DEFAULT
-------------------- --------------- ----------------- ----------------
-f, --font '<font name>' Choose font DejaVu Sans Mono
-s, --size <integer> Font size 9
-H, --header none Print headers true
-N, --no-header none ...or don't
-l, --line-numbers none Print line false
numbers
-L, --no-line-numbers none ...or don't
-d, --destination <program> Print handler lpr
-p, --pdf none same as
[Note 1] -d ps2pdf
with output to
'<basename>.pdf'
-o, --paps-opt --<opt> [<val>] Raw paps option --left-margin=75
[Note 2] (repeatable)
-O, --dest-opt --<opt> [<val>] Raw print option
[Note 3] OR -<o> [<val>] (repeatable)
-u, --usage, none Print this help false
-h, --help on the terminal
Notes
-----
[1] That is
$ printme --pdf foo.txt
is equal to
$ printme -d ps2pdf -O - - foo.txt >foo.pdf
or
$ printme -d ps2pdf -O - foo.pdf foo.txt
which have to be used if you want a different PDF filename:
$ printme -d ps2pdf -O - bar.pdf foo.txt
[2] For example
$ printme -o --right-margin 72 foo.txt
[3] For example
$ printme -O -P myotherprinter foo.txt
