I just got an HP 3050A on sale at Best Buy for $70. It will scan, print and copy. It is wireless. It works with the laptop, iPad and smartphone all via wireless. There's also some kind of cloud system or something. It's more techy than I am but I can print stuff and then scan the signed docs back into the computer to email to someone. It would work just the same to scan and email BOL's etc. to someone.
