Failed to print PostScript file

[Jabba Laci]

Hi,

Until now I could print my files from Vim using the ":ha" command. I
have the following in my .vimrc file:

"###############################
set printoptions+=header:0

set printexpr=PrintFile(v:fname_in)
function! PrintFile(fname)
 call system("lpr -h" . a:fname)
 call delete(a:fname)
 return v:shell_error
endfunc
"###############################

But now I get the following error:

E365: Failed to print PostScript file

In my shell PRINTER is set (to "[EMAIL PROTECTED]"), and in gv I can print
(with "lpr -h [EMAIL PROTECTED]") without any problem.

Do you have an idea how to solve it?

            Thanks,

                         Laszlo
