I saved an Excel file on my USB and since I don't own a printer I will print out at a kinkos or fed ex store. Problem is when I went to print it out and connected USB to the printers USB port file is no there. When I check on the computer is does show is saved there. Did I have to save in a different format or what am I doing wrong ?

Maybe look at last letters after the . On the file name does it say xls or xlsm makes a difference save as xls and most computers can read it fine.
