Printer Pooling becoming unckeched?

[roxaneamanda]

I have 'Enable Printer Pooling' selected within the printer settings but for some reason, something is causing this box to be come unchecked. I have tested aa couple of scenarios which do not result in the option becoming unchecked, eg switching off the printer, PC, unplugging etc. There is one thing which does uncheck this option which is when you use the safely remove hardware option. However, something is automatically un-checking this option when I am nowhere near the PC in question? Does anyone have any ideas why this is happening?
