Having trouble getting my printers to work with Wi-FI
New to Apple, I can't seem to get my Canon MX860 or my HP Laserjet P1102w to work by wi-fi? I have to turn off and turn on the HP before the iMac finds it each time I print. The iMac can't seem to find the Canon MX860. Since my new iMac did not come with an manual, I have no idea how to find our how things work. I am running OS High Sierra.
iMac (21.5-inch, 2017), from Windows 10 to iMac
