1. Quick Answer: Are QLN220, ZQ610 and ZR628 Printheads the Same?
No, they should not be treated as one identical printhead product.
From a technical replacement point of view:
| Printer Model | Common Printhead DPI | Common Replacement Part Number | Compatibility Judgment |
| Zebra QLN220 | 203 dpi | P1031365-070 | Same category as 2-inch mobile printhead |
| Zebra ZQ610 | 203 dpi | P1099875-016 | Not the same part number as QLN220 |
The Zebra QLN220 uses a 203 dpi printhead and is widely listed with part number P1031365-070. The Zebra ZQ610 also uses 203 dpi and has the same 1.9 in./48 mm print width class, but its commonly listed printhead part number is P1099875-016, not P1031365-070.
This means QLN220 and ZQ610 are technically related models in the same 2-inch mobile printer family direction, but their printheads should not be automatically considered interchangeable.
2. Why Are These Two Models Easily Confused?
The confusion mainly comes from three reasons.
- First, QLN220 and ZQ610 are both 2-inch Zebra mobile printers. Zebra's ZQ600 Series FAQ states that the ZQ610 is the 2-inch replacement model for the QLn220, while the ZQ620 replaces the QLn320.
- Second, both QLN220 and ZQ610 are 203 dpi direct thermal mobile printers with a maximum print width of around 1.9 in./48 mm. The QLn220 specification sheet lists 203 dpi and 48 mm maximum print width, while the ZQ600 Series specification sheet lists ZQ610 at 203 dpi and 48 mm maximum print width.
3. Technical Comparison: QLN220 Printhead vs ZQ610 Printhead
3.1 Zebra QLN220 Printhead
The Zebra QLN220 is a 2-inch mobile direct thermal printer. Its print resolution is 203 dpi / 8 dots per mm, and its maximum print width is 1.9 in. / 48 mm.
For replacement parts, the QLN220 printhead is commonly associated with Zebra part number P1031365-070.
From a service perspective, when a customer asks for a QLN220 printhead, the safest matching logic is:
Printer model: QLN220 → DPI: 203 dpi → Part number: P1031365-070 → Check cable and mounting structure before shipping.
3.2 Zebra ZQ610 Printhead
The Zebra ZQ610 belongs to the ZQ600 Series. It is also a 2-inch mobile printer with 203 dpi / 8 dots per mm resolution and 1.9 in. / 48 mm maximum print width.
However, the ZQ610 printhead is commonly listed with a different part number: P1099875-016.
This is the key point:
same DPI and similar print width do not automatically mean the same printhead.
A printhead must match not only the printing width and resolution, but also the FPC cable position, connector type, fixing holes, heating line position, pressure structure and printer firmware recognition environment.
4.Final Technical Conclusion
Zebra QLN220 Printhead, ZQ610 Printhead and ZR628 Printhead are not automatically the same product.
A more accurate conclusion is:
QLN220 and ZQ610 belong to the same 2-inch mobile printer application direction, and ZQ610 is the newer replacement-generation model for QLn220, but their commonly listed printhead part numbers are different. QLN220 is commonly linked to P1031365-070, while ZQ610 is commonly linked to P1099875-016.
