When printing Excel work sheets, do you get blank pages? There may be a few reasons for this. One frequently occurring reason is formulas, which result in blank cell values.
Press the Ctrl+` (unshifted ~, look left of the 1 key on the QWERTY keyboard) or click the Show formulas button on the Formulas tab. This reveals all formulas and allows you to see, for example, an IF statement, which checks for data in A1 before performing a calculation, =IF(A1=””,””,A1*B1). That would result in a blank value and appear as a blank row, unless you activated Show Formulas.
