Introduction
When replacing a printhead for a Zebra card printer, many users ask the same question: Are Zebra P310, P320, P420 and P520 printheads the same?
The short answer is: these printers are not the same model, but their printheads are commonly cross-compatible when the replacement printhead matches the correct part number and resolution. For many Zebra P310, P320, P420 and P520 card printers, the commonly referenced printhead part number is 105909-112, with 203 dpi resolution. This part is widely listed for Zebra P310, P320, P420 and P520 printers.
| Printer Model | Same Printer? | Printhead Compatibility | Common Printhead Part Number | Resolution |
| Zebra P310 | No | Compatible with same printhead family | 105909-112 | 203 dpi |
| Zebra P320 | No | Compatible with same printhead family | 105909-112 | 203 dpi |
| Zebra P420 | No | Compatible with same printhead family | 105909-112 | 203 dpi |
| Zebra P520 | No | Compatible with same printhead family | 105909-112 | 203 dpi |
Technical Conclusion:
Zebra P310, P320, P420 and P520 are different card printer models, but they can use the same replacement printhead when the printer version, connector, mounting structure and part number match. The most commonly referenced compatible printhead is Zebra 105909-112, 203 dpi.
Why Can Different Zebra Card Printers Use the Same Printhead?
Different printer models may share the same print engine platform or use the same thermal printhead module. A thermal printhead is not selected only by printer model name. The key factors include:
Part number
The safest way to confirm compatibility is to check the original printhead part number. For these models, the commonly referenced part number is 105909-112.
01
Resolution
The listed replacement printhead is generally marked as 203 dpi. Installing a printhead with the wrong dpi may cause poor print quality, incorrect image density or machine recognition issues.
02
Physical mounting structure
The screw position, printhead bracket and cable direction must match the original printer.
Connector and cable interface
Even if the printhead looks similar, the FFC/FPC cable and connector layout must match the printer's internal structure.
03
Printer firmware and version
Some legacy printers may have version differences. Before bulk purchasing, it is always recommended to confirm the printer's full model number and the original printhead label.
04
Global Printing Technical Recommendation
For Zebra P310, P320, P420 and P520 printhead replacement, Global Printing recommends confirming compatibility through three steps:
1.Check the original printhead part number
If the original part number is 105909-112, the printer is likely using the shared printhead type for this series.
2.Confirm the printer model and printer version
Some legacy machines may have regional or production-version differences.
3.Test before bulk replacement
For repair shops and distributors, sample testing is recommended before large-volume orders.
