Why don't gridlines show up in printouts?
The faint cell dividers that are clearly visible on screen vanish once you actually print β by default, gridlines aren't shown when printing, so you have to switch on that setting separately.
Check your print area setting too
It's also worth setting up a defined print area, so you only print the range you actually need instead of the whole sheet.
Frequently Asked Questions
Are gridlines and cell borders the same thing?
No. Gridlines are the faint on-screen guide lines, while borders are formatting you apply deliberately β for a crisper, more customizable look in a printout, borders are the better choice.
Will gridlines print even in empty cells with no data?
Gridlines only appear within whatever range is set as your print area, so it's best to set the print area to just the range you actually need.
