Computer does not recognize wifi printer
I just purchased a new cable service. I installed the modem (Motorola SB6141), and connected the most recent version of Airport Extreme. After some troubleshooting and lengthy rebooting of the modem (and router), I was able to get all devices to connect to the wifi network. I also have a wireless printer (Canon Pixma MG6220). After installing the new service, the computers and iPad cannot connect to the printer. I downloaded the most recent versions of printer and scanner drives, restarted the computer (Mac Pro), but to no avail.
If anyone knows what the next step should be, I'd appreciate it.
