DD-WRT allows for clientless printer sharing making it easy to install printers directly into the router without the need for a seperate computer. You must have installed USB support (usb_storage, sd_mod etc. can be left out if no need for external storage). Some of the information below is outdated. I made a guide for how to get USB printing working on the Asus WL-520gU. It should also apply to other routers with USB. http://wl520gu.googlepages.com/
