First stab I would take is disconnect that printer and verify you are using the latest driver downloaded from their website. Uninstall the driver/software you installed with the printer. But not a whole lot of information to glean from that error except for your USB stack is crashing.

I suspect the printer and related drivers are the issue however the pc won't stay on long enough for me to do anything. It boots then crashes again. I tried booting in safe mode, last known good configuration. Basically, I've done all I know to do.
 
Well, if safe mode is crashing, then you clearly have a HW problem. Remove any non-mouse/keyboard related USB devices when starting, and try and get into safemode.

The reason I suspect HW rather then RAM, is because very low addresses tend to be reserved for the system buses. So when I see an IRQL error and a VERY low memory value, I suspect HW before RAM. [Still, if all else fails, run memtest86 just to be safe].
