How do you determine if the printer is on line or not ?

You can call interrupt 17 (hex) to check printer ready.
I can't code this in Euphoria, as my pc is dead at the moment,
but here are the details:
load AH with $01 -- code to reset printer
load DL with $00 -- 0 = LPT1
call interrupt $17 -- printer interrupt
load AH with $02 -- code for get printer status
load DL with $00 -- LPT1 again
call interrupt $17
status returned in AH
No guarantees, but this has worked with most pc's I have tried over the
past 5-6 years.

Where is your printer?
Mine is next to my computer. When I turn on the computer, the printer makes
initializing noises. If the computer is already on, a glance at the printer
shows status lights on or off. Your computer must be in the next room or in
another building or something.
