I called HP support today because my printer wasn’t connecting to my computer over wifi. They told me to try deleting the printer and then adding it back in my computer’s system preferences. That did the trick.
About half of the time I have a technical problem, it seems like it’s solved by turning the troubled item on and off. Hitting reset.
How do you reset yourself?
With sleep? Fresh air? A swim? A weekend away? Do whatever works for you, but don’t forget to do it.
