Solution to HP (Samsung) Xpress M3065FW Printer Problem with OS 10.15.7

I just updated the OS10.15.7 in iMac with a security update. My Xpress M3065FW printer had been working well. After the update it started spitting out multiple pages with symbols and random characters on the bottom of the page. (BTW, This questions was addressed in Jan '21 with no solution.)

I have solved this problem.

I reset the printer system and reinstalled the printer driver via AirPrint.

The Printer Queue settings shows driver version 2.0. Still didn't work.

I have a macBook connected to this printer, running OS 11. It prints fine. The Printer Queue settings shows driver version 3.9.2

Some time ago I found this somewhere, "Samsung_Mac_10.15_Driver_V3.92.00.dmg." I don't recall where. Installing this package created a Printer Driver.pkg, but I couldn't get the installer to install drivers. I did get some folders which had a Samsung folder buried several layers down. Expanding several more zips revealed an M306x folder in Downloads with a Samsung M306x Series.gz. That expanded into the driver I needed.

I copied the M306x folder from downloads to the iMac Library/Printers/Samsung folder. Its Version.plist file says 3.92.

Whet to Printer and Scanners, Add. Selected "Other..." and navigated to M306x/Samsung M306x Series.

Clicked Add.

AND IT WORKS!

Unfortunately, I don't know where you can get Samsung_Mac_10.15_Driver_V3.92.00.dmg. Google doesn't find it anywhere. Perhaps someone can tell me how to upload it to a retrievable location for distribution.
