Activity Monitor reports that HP Device Monitor uses 2% to 6% CPU constantly, even when the printer is idle, and whether the connection is wireless or USB. It also reads and writes to disk every few seconds, even if idle. Is this normal? Is there a setting which will stop this behaviour? I ask because the iMac is elderly and a little slow (2.4GHZ Intel Core 2 Duo) and therefore needs all the spare CPU time it can get.
Thank you for posting on HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I came across your post and wanted to assist you. I see from the post that you are having issues with the Device monitor using CPU time even when it's idle. Don't worry I'll try my best to help you with this,
In this scenario, we cannot change the CPU time as it's system energy and device utilizing 2% to 6% is normal.
I hope this answers your question, let me know if you need any further assistance. I'll be more than happy to help.

So if I understand correctly, HP Device Monitor is a piece of software that runs all the time, waiting for a request from the user to print something; this uses up to around 6% of the CPU time, and is not a user option, it is switched on all the time. This means that the time from requesting the print to actual printing taking place is shortened.
An excellent feature in a professional environment, but it would be a benefit to users to have the choice of using it or not. For some customers, a few extra seconds waiting for a print to come out is not a problem, but sacrificing 6% of CPU is not a good option. This applies to home users particularly, and even more so when other devices such as scanners use a similar approach, so adding to the unwelcome loss of CPU time.
