Laserjet 1320
Microsoft Windows 10 (64-bit)

I wanted to update my Laserjet 1320 with the latest firmware. I installed and ran Download Manager(Ver 4.30) It identifies my printer as J8021A, current firmware V.40.06, needed V.41.19. When I select upgrade now, the Firmware Upgrade Results shows Successful upgrades:0 , Upgrade Failures:0.  Firmware upgrade is complete. It does not appear that the needed firmware version is being downloaded by the Download Manager.
