[comp.text.tex] tgrind and printing in duplex mode

uwe@bredex.UUCP ( BREDEX GmbH) (05/24/91)

Dear TeXperts,

I need some help (cause I'm not a TeXpert:-(.

I've modified the tgrind utility to add a clear page if a file has an
odd number of pages. I've done this because we usually are printing in
duplex mode and it doesn't look fine if the first page of a file
starts on the reverse page of the previous file. I got it to work, but
not without TeX warnings.

What I have done:
~~~~~~~~~~~~~~~~
I modified tfontedpr.c to print a "\Trailor{}" line after ervery file
being processed. 

In the tgrindmac.tex macro package I've added the follwing:

  \def\newpage{\par\vfil\penalty-10000}
  \def\clearpage{\newpage \write-1{}\vbox{}\penalty-10001}
  \def\Trailor{\ifodd\pageno\clearpage\headline={}\footline={}\fi}

I took this from the latex.tex package and modified it with some trial
and error until it works (yeah!). But I get TeX warning messages for
underfull \hboxes.

Any ideas how to avoid this warnings? 

Thanks in advance

uwe
