<pre>This is over a USB-parallel adapter. Things with dot 8 present don't
seem to be printing correctly. A capital b (dots 1 2 7) will appear
before each such character and frequently the printed character will
be offset by 0x80 from the desired, as iff the high bit was being
ignored. I suspect this is either a printer or Linux device driver
problem </pre>

Have you tried writing the file directly to the output device (i.e.,
under /dev), bypassing the printing layer just for testing purposes?<br>
