canon mf642 doesn't recognize on Macbook pro M1 (Big Sur 11.5.2)
I have connected to the same wi-fi and installed the latest driver, but the printer is not detected automatically. However, if you enter the IP address and search for it, the printer is recognized, but it is recognized as an unknown device. After reinstalling the driver several times, the printer was detected automatically, but the problem is still there. The printout is very blurry, or when printing a pdf document in adobe acrobat, the duplex printing function is disabled in the default print window. You can find finishig in the print properties and set up duplex printing, but it does not print by dividing the page by basic unit, but connects continuously to print on both sides. For example, if 3 pages are duplexed, 1 and a half pages will be the default page unit. If you are going to make three copies of two-sided printing of three pages, a new page starts on the other side of the half page instead of being printed in half. Who can't help in solving this problem?
