Well as far as my trusty string table of /usr/bin/lpsetup tells me, you
can look in /etc/printers.  Here's an excerpt:

25 27
ATT455 dumb Parallel
ATT457 dumb Parallel
ATT470 dumb Parallel
ATT471 dumb Parallel
...
ATT435 dumb_S Serial
ATT455 dumb_S Serial
ATT458 dumb_S Serial
ATT475 dumb_S Serial
ATT476 dumb_S Serial

The first number is the # of parallel printers, and likewise the second
number is the number of serial printers.  The format is:

PRINTER_NAME INTERFACE_NAME CLASS_NAME

lpsetup (running as setuid "lp") does a:

/usr/lib/lpadmin -pPRINTER_NAME -i/usr/spool/lp/model/INTERFACE_NAME \
	-cCLASS_NAME -v/dev/XXXX 2> /dev/null
enable PRINTER_NAME > /dev/null 2>&1
/usr/lib/accept PRINTER_NAME CLASS_NAME > /dev/null 2>&1

You can do this by hand if you like.

All the lp program does is run the output to a shell script (or INTERFACE)
in the /usr/spool/lp/model/ directory.  If you look at 
/usr/spool/lp/interface/Epson you will see it just has some shell commands.

If you need to do some "tricky" formatting stuff, the interface is where
to stick those commands.  (ie.  If you wanted to turn on compressed mode
for your printer, and you knew the escape sequence, you could just do an:

echo "\033\XXX"  replacing XXX with the escape sequence to do your function.

I thought this would be worthwhile for the entire net...
