Hide Taskbar - Point of Sale

Hello,

I am developing a Point of Sale program for my store. I have figured out how to print the screen but I need to hide the taskbar or make it invisible while the code takes a picture of my screen and then prints it. Then I would make it visible again.

I have tried several different suggestions on different websites but most of them use the word "long" and my laptop dosent recognise it.

Thanks,
Dylan
