After downloading "Bonjour for Windows" my WIndows 10 Laptop finally connects (in my printer dialog box my iMac is shown) with my printer connected to my iMac (Yosemite) which I have activated sharing. However when it prints, the page is blank. I was trying to print a test page for my Canon MP280 printer via my Windows10 laptop but still it's blank. The printer activates so there is a connection but it prints blank pages for all print jobs. Printing from my iMac is fine.
