One question: would that formula only work if the cell only contained the string "Pages printed: #"? I should have been more clear about this part, but there's a whole lot of text before that of varying length (file names, etc).

Yes.

This will check for up to 3 digits at the right of a string irrespective of what (if anything) goes before it:
Code:
=IF(ISNUMBER(VALUE(RIGHT(A1,1))),IF(ISNUMBER(VALUE(RIGHT(A1,2))),IF(ISNUMBER(VALUE(RIGHT(A1,3))),VALUE(RIGHT(A1,3)), VALUE(RIGHT(A1,2))),VALUE(RIGHT(A1,1))),0)
