There are several differences between the HP and the Epson worth mentioning. Both printers are network printers, meaning they support multiple users. Placing printers a little farther away from people will cut down paper use compared to putting printers at every desk. Believe it or not, some people will give up printing if they have to get up and walk. Politely put, that's conservation minded rather than lazy, but the paper use goes down either way.
Both printers support Windows and Macintosh users, but Linux users will prefer HP. Why? HP drivers are built into many Linux operating systems, while Epson is newer and less involved with the Linux community. My Ubuntu workstations can print and scan on the HP, but not the Epson.
The Epson includes wireless networking, but I don't recommend using wireless for printing. Wireless connections are always slower and less secure than wired, and printers stay still so mobility isn't an issue. However, if you have a mobile group that travels around, building your own wireless network that includes a printer will be handy. Since the wireless support doesn't cost more, don't worry about it if you don't use it.
You will need to load a CD ROM full of software to each computer that needs access to the multi-function printer. I wish some had print only drivers for users who don't need the scanning, but those are rare. Are you listening, printer people?
Stepping up to the next level means a dedicated scanner. Fujitsu sent me one of its ScanSnap S1500 Color Image Scanner units, and it's way cool. I got the PC version, but the company also offers a Mac version. The unit ties directly to the computer, rather than being on a network, which makes some sense. When you get one of these units you're more serious about scanning incoming documents for paper reduction and later retrieval. Assigning one person to be the Scan Master will lower mistakes and maintain scanning consistency.
The Scan Master will have an easy job. The ScanSnap takes up to 20 pages at once, and quickly scans front and back as the pages seemingly fall through the scanner continuously. While you can define each detail of a scan operation, by default the unit will scan in color if the page has color, eliminate blank pages, and keep the images in the order you feed them. It even scans business cards, which surprised me.
Street prices are around $450 for the unit I tested, which is thousands of dollars less than such units used to cost. One person with a ScanSnap can easily convert most incoming paper into scanned images that can be stored on a disk rather than in a cabinet. Searching and retrieval using searchable PDF settings for scanned documents works fast and reliably. Small companies can use this one unit, with the included software, and do what cost $100,000 ten years ago. That's a bargain, and reduces the amount of paper you have to store as well.
