About once a month, one of our school boards sends me a 50 page packet that I have to scan into .pdf format and e-mail out. We currently have an HP 5470C scanner that's at least 4-5 years old, and it sucks with .pdf format, even if I crank the resolution up to 2400, it's highest. After some complaints, I've been told to find prices on a new scanner to appease the old bats who can't read it. In looking at $300-$500 scanners, I've noticed that they're mostly 2400x2400 resolution, even the brand new ones. I'm scared that if I buy a nice new HP, it'll scan the .pdfs just as bad and then I look like a retard. What else should I look for in a scanner? Is it possible that the software I'm using (hp precisionscan pro 3.1) is causing the terrible quality? Thanks.
