ZPL
Dots = inches × DPI. A 4 × 6 label at 203 DPI is 812 × 1218 dots. Printing at the wrong size
is the #1 reason labels come out shrunk. PaperReady prints at true size to any installed
printer, so what you set is what comes out. Get the free agent →
Frequently asked
What is 203 DPI in dots per mm?
203 DPI ≈ 8 dots/mm, the most common desktop thermal resolution (Zebra ZD/GK, Rollo, many DYMO and MUNBYN). 300 DPI ≈ 12 dots/mm for finer barcodes and small text.
How do I set the size in ZPL?
^PW sets the print width in dots and ^LL sets the label length in dots. Drop the values above into your format between ^XA and ^XZ.Why does my label print shrunk to a full page?
The app is scaling it to letter or A4 instead of printing at the label's true size. Print through a local agent that targets the label printer directly, which is exactly what PaperReady does.
