Printing at true size (why labels shrink)
If your 4×6 label prints small in the corner of a big page with a barcode too faint to scan, the cause is almost always scaling, and it's the exact problem PaperReady removes.
Why it happens
When you print from a browser or PDF viewer, it treats your label as a document and fits it to the default paper size (US Letter or A4), adding margins. A 4×6 becomes a small rectangle stranded in white space. The "Fit to page" / "Shrink to fit" option is the culprit.
How PaperReady prints true size
The app sends the job straight to the label printer at the label's real dimensions, bypassing the browser print dialog entirely. A 4×6 stays 4×6, edge to edge, with a crisp barcode. Nothing is scaled to a page.
