Unless the has a dedicated print server I don't think that you can connect your printers directly to this router, I think you will need a print server.
This would connect to one of your routers lan ports, then connect the printers to the servers, set it up and you will be able to see the printers on any pc on the network (you would have to install the printers drivers to each pc you wish to use the printers with).
Make sure that you get the right one, many of the p/servers I have seen have only one usb port.
Here's a froogle search for print server, you will have to wade throgh the listing till you find the right one, at the right price.
Hope this helps.
