I opened my Printer folder on the PC and shared it as you suggested. I then went to print a document from the laptop, but the printer doesn't show up as an option....
I still don't think the devices are communicating with each other...i.e.: are they really on the same network? See my 9:30 post....
Yes they're on the same network. If you want to make sure, get the internal IP of each PC, and try to ping each other from command prompt. If you get a reply, then it's on the same network.
As for the printer issue... You need to add the printer on the laptop through Devices and Printers. And then browse to your other PC over the network (it may automatically find it in the network printer list as well if you've properly shared the printer).
