I don't know which ActionTec router you have, and I find the manuals don't provide a clear answer anyway. It doesn't appear, however, that the USB supports a shared printer (at least on some of the routers). If your printer does not have Ethernet or WiFi support built in, however, you probably can still share it over the network. Check Amazon for "print server USB" and you'll find a number of choices for less than $50 that should do the job for you.
