Cannot sync table with chart

Good Afternoon

I was wondering if someone could help, my minds gone blank and I seem to be finding it hard to figure this out.

I知 trying to make a excel spreadsheet using data provided from my colleagues, this is an activity list of there print jobs.

Next to this data i want some sort of chart to show how many times a certain printer is being used, but calculate it as it gets input. I.e as the data gets inputted as soon as they state there using a certain printer when enter is pressed this will add on to the chart.

Any ideas, I've attached a screen print of what I知 trying to do to give you guys an idea of what I'm doing (well I hope)?

Many thanks
