Unless the requested 42 pages were formatted and prepared for letter size, I don't see why they would be asking you print them on letter size. It would scrunch all the letters and possibly make it look trashy too.
Now, if the edoc package is mixed, some letter and some legal, then that's a different story. And that's where a dual tray printer may come in handy.
In the past, when I had the time, I would print everything on legal size paper and then cut the letter size ones with a paper cutter. Just a thought. |
