How to get rid of unwanted HP printer Utilities?

If you replace an old HP printer with a different brand that may leave tools for the previous model hanging around and cluttering up Launchpad. Trash any alias to them from Applications/Utilities, before removing the folder named ‘hp’ in Library/Printers.

Why won’t my Wi-Fi printer use 5GHz?

Some older printers don’t support the 5GHz Wi-Fi standard, or may be incompatible with new devices operating at that frequency. If they have problems, they should automatically switch to 2.4GHz, but you may need to give them a hand by ensuring your Wi-Fi base station supports both 2.4GHz and 5GHz bands.
