Q: inkjet 4 memory hog

If I were you then I would navigate to hp's homepage and look for their latests driver for their 309A model

if their drivers had issues then they have likely make a new driver which fix it

Ps - apps such as "Memory Cleaner" are totally unnecessary. Any memory held in an inactive (blue) state has been previously used by an application, but is now available for use for any application that needs it. If the original application is re-launched, it will operate more quickly for having its data already in RAM.

It's a misconception that you need to have a huge swathe of free (green) RAM for your system to operate well. Free RAM is not being used at all and is wasteful. Provided your total free + inactive RAM is sufficient for any programs you wish to run, the system should be fine.

Also, don't pay attention to the "VRAM" amount in a running process - that does not reflect the true amount of RAM used from your total.

I just had this problem as well. Activity Monitor listed inkjet4 as the culprit running up the CPU--( fans were on non-stop full-blast and the whole system was sluggish.  It was driving me bonkers.

Unbeknownst to me, there was a document in the queue for one of a printers that wasn't plugged in. Once I deleted the doc from the queue, all returned to normal with the system.

I was able to view all the various printers and their queues in system prefs/ print-scan.

Hope this helps someone.

Saludos.

Thanks!

My wife's Mac Air was spooling some enormous file (for days) to the shared HP and the inkjet4 process was busily growing as a result. Thanks for the pointer.
