How to get printer dialog in GVim on Linux?

Question

Sometimes I like to print some code to understand it. Clicking on the Print button in GVim on Linux prints to the default printer with some default settings.

How can I get the standard printer dialog when I want to print from GVim?

This is so that I can choose a printer (from multiple printers available on the work network) and change other print settings (duplex, pages per side, etc).

Answer 1

See :h hardcopy and :h print-options.

You can set the set the printer using :set printdevice=xxx and other options using :set printoptions=xxx.

If you really want to use the dialog box you could print to a file then open that file from some other program to print it :hardcopy > output.ps

Answer 2

To obtain a print dialog upon printing in gvim, you can add the following to ~/.vimrc:

set printexpr=PrintFile(v:fname_in)
function PrintFile(fname)
  call system("kprinter " . a:fname)
  call delete(a:fname)
  return v:shell_error
endfunc

Instead of kprinter, which is the print dialog from KDE3, you can also use gtklp or whatever is the the print dialog command of your desktop environment.
