The problem with that approach is that it won't always work (without a
full-blown report writer). Writing the information to a disk file and
then simply dumping it to a spooled file doesn't account for the more
advanced features of printing.

You would need EXTENSIVE formatting type information for various
attributes, etc. Not to mention the problems with overlays, barcodes,
etc.
