Message that connected printer's driver is unavailable despite downloading driver

[AllredTA]

HP Envy Pro 6455 printer that I've used for years won't print.  It is connected to my home network/computer but the error message says the driver is unavailable.  I use HP Smart, but that does not resolve the problem.  I downloaded the driver from 123.hp.com and that also does not resolve the problem.  I continue to get the message that the driver is unavailable.  Suggestions?  Thanks.

The full feature software of April 2024 is available.  Maybe that will help

In case you need to reconnect to the network.

A hard reset requires the cartridge door be open

If no smartphone then use the WPS or pushbutton method discussed on page 28 of the users manual

InkJet Reference
This printer supports 2.4 and 5ghz bands.  If you have problems with it disconnecting from the network I recommend you set it to use only the 2.4ghz band.  At the printers control panel look for the option to select 2.4, 5ghz or "auto" and select 2.4. If the printer does not have those options then you will have to log into the modem and rename one of the bands.
