how to uninstall and reinstall drivers

[Ted-h]

My HP Envy 4527 printer just stopped working.  The troubleshooter confirmed that the WiFi connection to my computer has failed.  How do I install a new driver?

Hi Greenturtle,

Many thanks for your reply.  My Computer is an Acer Desktop and my printer is an HP ENVY 4527.  They suddenly stopped talking to each other and I could not find out why.  I tried uninstalling and reinstalling the software as you suggested.  I bought a USB lead and tried that.  No good, I'm afraid, and I have come to the conclusion that there is a fault in the computer - even though everything else is working perfectly.  The Troubleshooter could find nothing wrong with the printer.

I have no option but to call in an expert to sort it out for me.

Best Regards,

Ted.h.
