I have my HP psc1350 connected to my desktop PC (Windows 7) via USB and my laptop (Windows 8.1) can print to that printer over both the LAN and WiFi. I can also used the scanner from the Desktop machine. My problems is that when I attempt to use the scanner from the Laptop I get a message is the Scanner turned on? I also tried to reload the drivers for the all in one on to the laptop and again the installer is not able to locate the device even when I tick the it's on a LAN box. I had this problem with windows 7 and now I have it with Windows 8.1. I have tried with the built in Scan Programme and Microsoft Office document scanning. Each time I states no compatible scanner found, load software. How can I over come this? Is this a network problem?
