I can't find the print screen key in my loptop please help me

What make is it as the location varies ?
Normally it's in the Top Right quadrant.

That's strange. It usually is on the first row where all the F1 and F2 keys are. Maybe you just missed it.

Its usually located up the top of your laptop keyboard on the right hand side, next to the PAUSE BREAK button.
The letters on the Print Screen button are: PRTSC
SYSRQ

There's 2 rows of lettering on the key itself. Look for those letters on a key and you've found it! Remember to use "CTRL + ALT" when trying to do a screen print. :-)
Alternatively, Google "Image: laptop keyboard" and zoom in to help you find it.

On a laptop you may have to press a "Function" or "FN" key that shares the color of the print screen button label.
