PRN file viewer
A .prn label file is usually plain ZPL or EPL saved by label software. Press Open file above and pick the .prn to see the label and download it as PDF or PNG, with nothing to install.
Your file is downloading.
Free, with no daily limit. A free account also saves your designs and gives you an API key.
What is in a .prn file
PRN means "print to file": the exact bytes the program would have sent to the printer. For a Zebra that is usually ZPL, which starts with ^XA. Open the file in a text editor to check. A file for an older Eltron printer holds EPL, which the EPL viewer opens, and one for a TSC printer holds TSPL, for the TSPL viewer.
When it won't open
A .prn from a laser or inkjet printer holds PCL or PostScript, which this viewer doesn't draw. If the file starts with unreadable characters, that's probably what you have.
