Problem getting printer to work

Hi,

I have a Versalink C405 linked through the wifi. I had the printer working fine for the last year or so, but recently had to reset Windows after a problem with an update. Since then I've struggled to get the printer to connect to my computer. I install the drivers, using "Smart Start" and the printer is visible and installs fine. It will then print fine for a short period of time, but then maybe the next day it stops working. The printer is still visible, but when I try to print it sits in the queue and then just reports an error. Any ideas? 

Thanks,

Ben
