Printing a table in Numbers

Just trying to print a table onto 1 maybe two pages but no matter what I do, the margins take up the whole page almost when in print preview. The printing is so small that it impossible to read and prints a row several pages with mostly just white margin area of most of them. I have tried to adjust all possible ways. ????? I am using iPad Pro to an Hp printer. Does anyone know what could be adjusted? Please.
