Summary: you can also do it with an escape and post-processor

Since we don't have a source licence for the system that uses our 
laserjet, I used a different approach: an escape code which indicates
that the next character should have its high bit set. The program is then
sent thru a post-processor (in the 'lp' driver) which eats the prefix char
and bit-twiddles the next character).   The nice thing about this is that
it requires no source license.   The bad thing about it is that there areis 
then two characters that cannot be sent to the printer: 0x80 and your escape
code. (0x80 would require being able to embed a null char....).

    If anyone is interested in this kludge, send me a message.
If I get enough requests, then I will just post it.
