Compressed Text

[Pickering, John (NORBORD)]

Jim

I think the idea of a simple "compress ON/OFF" switch is a bit simplistic
today. In the ancient days of HP2932 impact printers (when Quiz was born)
with a couple of fonts and 3 sizes (compressed, normal, expanded) you could
do things this simply. But with newer LaserJets (like the 8000) you have a
much richer set of fonts and nearly all of them are scalable. You'd be
better off explicitly coding the PCL for the font and size you want for your
"compressed" text and another for the "regular" text. Then use these 2
strings as the ON and OFF switches respectively. The printer will happily
print a list of all its fonts and the PCL needed to invoke them.
