Very slow printing on 5.4 with cups anh HP LaserJet 4L

[MarkNevada41 at aol.com]

how did you change the setting?
 
My 932c used to print 3 or 4 lines per pass and now it does one line per  pass

I had the exact same problem, except with a Deskjet  932C.  Someone on the 
list said "man lptcontrol" and set your printer  to "poll".

I used this command:
% lptcontrol -p -d /dev/lpt0
and it  fixed my problem.
 
 
where so you install the command?
 
thanks,
