Unfortunately, the problem has reappeared. I went to print today and while the printer didn't show as "offline" Control Panel>printers, when I tried to print a PDF, nothing happened. I then tried to uninstall all instances of HP on my computer and did so. I then tried to install the software from my disk and noticed that there was an red x showing that the printer driver didn't install but other drivers did.
So I'm now going to try to use the link that was sent here for the most updated installation and see if this takes care of it. Unfortunately, I'm applying for a job and need to print the pdf so I can fill it out then scan it into a file and send it from my computer to the company's email address. If I can't get this thing to work, and I'm really beginning to hate HP, I'll have to go to Staples and do it from there. I can't imagine why this is happening. The printer worked fine until I received an update request from HP. After that, all this nonsense started up.
