Hi again.
So my HP MFP 4301fdw color laser printer/scanner stopped working after the latest Windows 11 update. I got it to work again for awhile after uninstalling, redownloading all the software and reinstalling. Worked for about a week then failed and then the same process would not work again. Finally found the following thread on alternative scanning software and downloaded the shareware naps2 and it has been excellent. Easy to install and loads very quickly (the HP scan software took like 45 seconds to load even when it was working). The only thing I can't seem to figure out is scanning two sided documents (duplex). It's supposed to do that but can't make it work. That's rare for me so I can live with it. I'm assuming HP or Microsoft will solve the issue at some point. This works very well in the meantime. Bottomline, there are many scanning software options out there. You don't have to use HPs. And the others actually work!
Good luck. I know how frustrating this is when you're just trying to get work done.
