As far as I know there is no way to tell if 'lptest > /dev/[u]lpt?'
will produce anything given some random printer. The ASCII is what the
printer would see from MS-DOS's native printer driver so I would not
expect future printers to retain this ability for very long (some have
not). If a printer works with MS-DOS, the lptest would also certainly
work too.

A better test involves using a ghostscript filter (because that is what
you are going to use most likely anyway). The guide should probably
mention that using the raw ouput from lptest won't always work.
