[SLUG] cups colour and a vimrc trick

[Ken Foskey <foskey@xxxxxxxxxxxxxxxx>]

First the trick,  Jeff might like this for his .vimrc.  I have been
reading manuals again.

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

Calls cups client for printing,  allows printer setup.

My problem is that the HP dj 670C colour cartridge is stuffed (I am
guessing) and I cannot get any colour out.  I cannot switch the printout
to grayscale and make it stick.


Any hints.
