I just 'binged' the term pictbridge paired with Printer and Scanner... Pictbridge is a standard designed to allow digital cameras to print directly from the chip without using a PC. Lots of home and SoHo type printers and MFP's include pictbridge. If you want a scanner for documents, particularly with a sheet feeder, you'll need a 'real' scanner, and it will either be designed to interface directly with a PC (new ones are all USB, older ones were SCSI and variants of it), or it will be business class MFP that will scan and email you the results.
We have three of the networked MFP's on our floor, and they get heavy use. You can print directly to them, use them as a copier, or scan and have the results in your email inbox.
Scanning and document capture is a large part of what I do. I have access to dedicated scanners, but I use the scan-to-email feature of our MFD's a lot! Scanning to print uses a dedicated device called a copier!
