Before I start, I know my printer is old, but it prints beautifully and I like it. I've had my HP Laserjet 4+ for 11 years and it's never missed a beat.

I now have a wireless router providing a network for one wired PC and wirelessly for 2 PCs and a Mac and I'd like for these other computers to be able to print.

I.ve splashed out and bought a Jetdirect 2552-60003 print server card from Ebay for a whacking 99p, but it came with no instructions or discs and the help on the HP website may as well be written in Chinese.

How do I get the printer card recognised on the network so that all four computers can print?
