There are hundreds of things that can go wrong
Troubleshoot printing and scanning issues with HP Print and Scan Doctor | HP Printers | HP Support
I am a huge fan of HP printers and I think they are generally the best printers for both business and consumer use. However, they come with some of the worst software possible that not only bloats and slows down your system but also doesn’t really help in connecting your computer to your printer, which is the main purpose of any printer.
Many printers these days are wireless or at least network-enabled, meaning you can plug in a network cable and print without actually connecting the printer to your computer via USB. It’s ridiculous to buy a new printer today and be forced to connect it to your computer before installation.
Unfortunately, setting up a network or wireless printer is much more complicated because you now have to deal with all sorts of equipment between the two devices. Even if you can print to your wireless printer today, you won’t be able to in a month if the IP address accidentally changes or someone turns on a security feature on your router that prevents communication between devices on the network. There are literally hundreds of things that can go wrong.
