I find myself unable to connect my High Sierra MacBook Air to my M4250 Cannon printer (both work fine separately). I've donwloaded and installed several drivers from https://www.canon.co.uk/support/consumer_products/products/fax__multifunctionals/inkjet/pixma_mg_series/pixma_mg4250.html?type=drivers&language=&os=mac%20os%20x. Not sure which one I should choose.
The driver named "ICA Driver 4.0.0.a" is installed successfully according to the installer, but is nowhere to be found in
The one called "MG4200 series CUPS Printer Driver Ver. 220.127.116.11 (Mac)" installs correctly it seems but when I launch it (with the printer turned on and connected to my laptop via USB cable) I always get the following error alert :
Cannot communicate with scanner for this reasons : -Scanner is turned off. -USB cable is disconnected. -Printer is in use or an error has occurred. Please check and try again. Scanner driver will be closed. 2.156.0
Rebooting does not fix the problem. Any help appreciated.
