Printing a series of numbers

[Brian Yennie]

Jerome,

Would it work to make each page a separate print job? Then you keep  
sending print jobs until one fails. The next day you just cancel the  
last failed job.
Something like:

Print "5"
Print "6"
Print "7"
FAIL

Next day...
Print "8"

That way you are not worrying about detecting "out of paper" in the  
middle of a multipage job. You just wait until a 1 page job fails.
