lpr output filters

Re: using the special user `viewer' approach, with the desired files
owned by `viewer', and mode 400.

What if I first run `script', then use the viewer setuid program to view
the files? I would then have the output in `typescript'.

Or, if a run a terminal emulator with memory (like xterm, or cmdtool),
I can just cut and paste the window output to another window/file.
