Printer languages

Native means the printer's own language. Emulation means a separate, manufacturer-documented mode that accepts another vendor's language — useful, but not the same thing.

What this means in practice

ZPL, EPL is the printer's own language here, so jobs written for it run without a translation layer — the closest thing to a predictable result.

This body ships in more than one resolution (203/300 dpi). ZPL coordinates are in dots, so a label designed for one resolution comes out at a different physical size on another — check which unit you actually have before sending production jobs.

Anything positioned beyond 104 mm of print width will not appear on the label; the compatibility checker flags this for the ZPL job you paste.
