Hello Byzantinechurch,
In Numbers, you will see additional print options after you choose File > Print that can change how your spreadsheet appears. We recommend reviewing these options to see if this could be the cause. Print a spreadsheet in Numbers on Mac has more information.
"Set other print options:
- Page Orientation: Numbers uses portrait (vertical) by default, but you can choose landscape instead.
- Content Scale: By default, Numbers scales your content so that it fits the width of one page. To display content across multiple pages, drag the slider to adjust the scale. To fit content to the width of a page again, click Fit. (If you open a spreadsheet from Numbers ‘09, Fit is turned off by default.)
- Repeat table headers: Select the checkbox to print table headers on every page where the table appears.
- Print comments: Select the checkbox to print comments. Comments appear on a separate page that follows the sheet. Comment flags on the sheet are numbered to correspond with the comments on the comment page.
- Print sheet background: Select the checkbox to print the background color of the sheet. If you turn off sheet backgrounds, all text colors for the sheet are changed to black. This option appears only when you change the sheet background.
- Page Numbers: Page numbers are printed by default. To continue page numbers from the previous sheet, select “Continue from previous sheet.” If you select “Start at,” type a starting page number. If you don’t want a page number to print on a specific sheet, click the center of the footer on the sheet thumbnail in the grid on the left, select the page number, then press Delete on the keyboard.
- Page Order: Choose whether pages are numbered top to bottom, then left to right, or left to right, then top to bottom.
- Page Margins: Enter values or click the arrows next to Top and Bottom to set the page margins."

Take care!
