ZPL vs EPL: Differences
Comparison between the two main programming languages for Zebra printers
ZPL or EPL?
Zebra Technologies developed two programming languages for their printers: ZPL (Zebra Programming Language) and EPL (Eltron Programming Language). Although both are used to create labels, they have important differences that affect their use.
Comparison table
| Característica | ZPL | EPL |
|---|---|---|
| Year of introduction | 1990s - More modern | 1980s - Older |
| Syntax | Commands with ^ and ~ | Commands with simple letters |
| 2D barcodes | Full support (QR, DataMatrix, PDF417) | Limited support |
| Graphics | Advanced image support | Basic capabilities |
| Fonts | Multiple scalable fonts | Limited bitmap fonts |
| Compatible printers | Modern Zebra models | Older Eltron/Zebra models |
| Documentation | Extensive and up-to-date | Limited and legacy |
When to use each language?
ZPLUsar cuando...
- Modern Zebra printers (ZD, ZT, ZQ series)
- Need QR codes or DataMatrix
- Require complex graphics or images
- New developments or projects
- Integration with modern systems
EPLUsar cuando...
- Old Eltron printers
- Legacy systems already using EPL
- Very simple labels without graphics
- Compatibility with existing code
- Specific hardware restrictions
Recommendation
For new projects, ZPL is the best choice. It offers more features, better support, and is compatible with all modern Zebra printers. If you have existing EPL code, consider gradually migrating to ZPL to take advantage of current technology.
