Epson SX600FW set up to Dell laptop fine but won't print from HP laptop (Windows XP)
 

Hi everyone. Newbie here, hope you can help.
I recently purchased an Epson SX600FW Wireless Printer and tried to add it to my home Wireless network via my HP Compaq nc4400 notebook. It appeared to work and the printer is recognised however it won't print. I then tried my Dell laptop and it works fine.
I tried both Epson & HP helpdesks who blamed each other!!
Does anyone have any suggestions for resolution???
Thank you!!
