Photosmart C4780 driver update in Windows 7

Photosmart C4780
Microsoft Windows 7 (64-bit)

My computer suddenly could not find the above printer today. I ran the computer's troubleshooter, and it gave the message "The print spooler isn't running." The troubleshooter could not fix the problem. After a bit of Googling, I went to Services/Run as Administrator/Print Spooler/Properties and set the startup type as Automatic under the General tab and selected Restart the Service under the Recovery tab, and finally clicked Start the Service in the left-hand column of the Services list. The print spooler, however, could not be restarted. I Googled a bit more and then tried to update the drivers, but they would not update because the print spooler was not running. So, I uninstalled the printer altogether and tried updating the drivers again, with the same result. This seems to me to be the classic Catch 22: I can't start the print spooler without updating the drivers, and I can't update the drivers without starting the print spooler. If anyone has an idea, I am all ears (usually, I'm all thumbs). I'm beginning to wonder whether the problem is that an automatic update was no longer compatible with the woefully outdated Windows 7. I am loathe to update to Windows 10, since I have never, ever heard one good thing about it and i am afraid that a number of my more specialized programs won't work on it. Have I reached the point I have to make the dreaded update nonetheless?
