I have a sharp El 1701C calculator and can't get it to print. It was working but I touched some button and now it shows NP, also an F and a up arrow on the left side of the screen.

I think you might just have shut it off.
Press '2nd' then M+.
P/NP = Print / NoPrint
the '2nd' button will allow you to choose the fonction on top of the M+. I think you might just have shut it off. Press '2nd' then M+. P/NP = Print / NoPrint the '2nd' button will allow you to choose the fonction on top of the M+.

the F is for the decimal. ( wich you can set as F-Floating, 3 decimal, 2decimal, 1 decimal, 0 decimal. A- the number will be in the decimal if you dont put a '.' )
the arrow is the way its rounding the numbers the F is for the decimal. ( wich you can set as F-Floating, 3 decimal, 2decimal, 1 decimal, 0 decimal. A- the number will be in the decimal if you dont put a '.' ) the arrow is the way its rounding the numbers
