How to decrease the size of shipping label

I use Firefox as my browser and print plain paper laser labels.

When using Firefox, the printed labels are sized according to the scaling set in the Firefox browser.  Before printing a label, got to the browser menu bar

File > Page Setup

uncheckmark "shrink to fit" and set "Scale" to "100%"

The size of the "100%" label is less than a half sheet of paper (about 6x4). Avoid going too small or the bar codes will bleed together and won't scan properly.
