I put accurate timing options into card and printer devices a while

1,000 LPM from a printer is noisy and you see the paper flying by. But
some quick math reminds
us that a typical 55 line page means 18 pages/min, so your 100 page
listing takes about 5 1/2 minutes
to print. If you're the first job in a queue.
Timothe,
As far as I can tell, the PDP-11 I'm running is as fast as the Macbook
Pro I'm running it on and I like it that way :). 5 1/2 minutes for a
listing? Ouch.
Well, you need to understand that 5 1/2 minutes is not because of any
processor speed issues.
It's just physical limitations of a line printer. Simple math...
If your printer prints 1000 lpm, 55 lines per page, means 18 pages/min,
means 100 pages takes 5 1/2 minutes, like Tim wrote.
Any CPU could easily produce data faster, but the printer will still not
print it any faster than this.
