* Canon has launched the WP-20 Wireless Print Server which lets multiple users share the same printer. The Print Server is aimed at homes with wireless networks that use the wi-fi standard (IEEE 802.11b) and wired networks that use Ethernet. The WP-20 uses a USB connection. Canon claims that once the print driver is installed, a set-up wizard makes the server fully operational on most home networks. It costs pound;139 (inc VAT).
