Hi ajc211,
The MP620 has been retired and is not supported with the OS Catalina operating system. The last drivers that were made for this model printer were for the OS X Maverick operating system.
Since the printer has been retired, you qualify for the Canon Upgrade program. This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system. This program allows you the opportunity to purchase a replacement product discounted from the list price. Free ground shipping is included with your purchase.
If you would like to take advantage of this offer, please call our Sales Department at (866) 443-8002 mon-Sat, 9 AM to 9pm EST. Let them know you have been working with technical support and that the Canon Upgrade Program was offered.
