Because you dont have a printer?
Seriously -- you need to be a tad more explicit in relating your problems
Do you have a printer hooked up?
Is it on?
Have you verified that the printer is installed on your computer?
Can you print from other programs?
Do you have this printer selected as default printer in Excel?
Do you get any error messages? If so, what do they say?
: why every time i'm using excel i can't print????
