So, [Esc](sB was the sequence to turn on 'bold' or bright on those
terminals? Of course, that's different from our beloved 700/92s.

The other things that I found curious is the number of hits that I found for
"(sB escape" on google, with references to turning on bold, for a number of
non-hp printers. I'm guessing that most or all of the other printers I found
googling are someone's clone supporting PCL. Can someone tell me if they
have line printers that use this escape sequence?

And, the file that I am looking at, appears to be designed for someone's
line printer, at 66 lines per page, or 6 lpi. Dumb spooling, like John
referred to, with no channel skips of any kind. Just line after line of
fixed-width text, with just this one pair of escape sequences on the
occasional line. Many of the pages do not even that them. I can send it to a
LaserJet, and it does print reasonably well, although not at 66 lines per
page.
