To get this to work you have to know how many lines per page :hardcopy is normally making. Open empty document and in Normal mode "100o". Then make ":%s/^/\=line('.')". Now ":hardcopy > nu.ps". Open nu.ps in PostScript viewer. You will see how many lines per page Vim is printing.

In my case this is 73. Now set the 'printheader' option:

:set printheader=%<%f%h%m%=Page\ %N\ of\ %{line('$')/73+1}

line('$') - number of lines in buffer
73 - number of lines per page
+1 - Vim uses integer math and everything rounds down.

I forgot about case when total number of lines is multiplication of lines per page. Here is an improved version. Number of lines per page was put in variable - you have to change it only once.

function! PH_Multiple()
  let lpp = "73" " lpp - lines per page
  let modulo = line('$') % lpp
  if modulo != 0
    return ( line('$') / lpp ) + 1
  else
    return line('$') / lpp
  endif
endfunction
set printheader =%<%f%h%m%=Page\ %N\ of\ %{PH_Multiple()}

Some nice additions from comp.editors:

:set printheader=%<%f%h%m%=Page\ %N\ of\ %{line('$')/73+(line('$')%73!=0)}

:set printheader=%<%f%h%m%=Page\ %N\ of\ %{(line('$')-1)/73+1}

Clever; however there are multiple settings (see e.g. 'printfont' & 'printoptions') which can change the number of lines per page. Also, if long lines wrap when printed (the default), then the number of lines in the buffer may not match the number of lines printed.

A simpler way to do the page count arithmetic:

:set printheader=%<%f%h%m=Page\ %N\ of %{(line('$')+72)/73}

+Clever; however there are multiple settings (see e.g. 'printfont' & 'printoptions') which can change the number of lines per page. Also, if long lines wrap when printed (the default), then the number of lines in the buffer may not match the number of lines printed.

-Peppe Guldberg:
-:set printheader=%&lt;%f%h%m%=Page\ %N\ of\ %{line('$')/73+(line('$')%73!=0)}
-NOTE: smart use of condition
-Anthony:
- :set printheader=%&lt;%f%h%m%=Page\ %N\ of\ %{(line('$')-1)/73+1}
-IMO this is best of all: oneliner and number of lines appears only once - easy to correct.
-Thanks!

-Given these limitations, it would be great if the 'printheader' header option was extended (Vim 7?) to handle this in the Vim code itself. Maybe %T = Total number of pages to be printed.
