It is 10:45 and have just managed to print the first document wirelessly with this printer. What is it about these things that cause so much trouble to some people I don't know but a degree, a masters and a PhD seem of little help when you try to install a device like this one. Manufacturers have now decided that manuals and prospectuses are a thing of the past and that consumers have a responsibility to dig out from innemrable HELP websites solutions to their problems. A shame. This printer comes with a quick set up guide which is entirely useless for wireless set up (it doesn't even tell you the function of the WPS button) and a longer guide that is rinted so small I found it unreadable (I use readyreadrs 1.50 and my eye sight is not normally hopeless).
I installed this printer using the USB connection very quickly and painlessly in 3 minutes (round about 3pm). Windows XP picked up the software from the necessary website and the printer was up and running smoothly. Connecting it wirelessly has take some five hours of frustration and maybe I can save some other people a little time with the following tips.
If you install the printer directly with the USB connection, you will have to uninstall it before you can install it wirelessly.
First make sure that the printer has recognized the router, by pressing the WPS button persistently (3-5 seconds) AND ALSO the WPS button on your router (if it has one).
To install the printer wirelessly on your computer, you will still have to use the USB connection but MAKE SURE THAT THE PRINTER IS FIRST WIRELESSLY CONNECTED TO YOUR ROUTER. I spent a good half hour before realizing that once you have plugged the USB on you computer, the printer is unable to make contact with the router, UNTIL IT HAS BEEN FULLY INSTALLED.
After installation was completed (and this took several false starts), the computer had to be rebooted before it could connect wirelessly with the printer - something that nobody told the first time user.
