🧠 1. Basic Meaning of These Part Numbers
Honeywell/Intermec printhead part numbers such as these represent different versions of the thermal printhead assembly for the PM4i / PF4i series printers. The main reasons for different part numbers are:
Different print resolutions (DPI)
Media thickness range or head design
Mechanical variants (offset, centered, or thick media support)
📊 2. What Each Specific Part Number Indicates
👉 1-010043-900
203 dpi printhead (8 dots/mm).
Standard head for PF4i / PM4i printers.
Rated for typical media thickness (e.g., up to standard ~175–180 µm).
Common OEM standard part.
👉 1-010044-900
300 dpi printhead (higher resolution than 203 dpi).
Provides finer, clearer text and graphics.
Also standard media thickness head, but different heating element density.
Required when your PM4i/PF4i printer is configured for 300 dpi.
👉 1-010043-910
203 dpi head for "thick" media (higher allowable media thickness).
Designed for heavier label stock / tag stock requiring different thermal gap/pressure characteristics.
Sometimes labeled as "Thick RoHS" variant.
Historically marked as EOL (no replacement) in some catalogs.
👉 1-010044-910
300 dpi head for "thick" media, similar to 1-010043-910 but with higher resolution.
Used when printing fine detail on thicker labels or tags.
Often specified in parts lists where thicker media is required.
👉 1-010045-900
203 dpi head with an offset or centered mounting variant.
Mechanically slightly different (e.g., element position shifted/centered compared to standard).
Designed for a specific media path or sensor alignment in some PM4i/PF4i models.
Optionally preferred when standard heads don't align with a specific printer's mechanical setup.
🧩 3. Why There Are So Many Part Numbers
✅ Resolution Differences
203 dpi vs 300 dpi → different part numbers because the heating element density changes.
DPI impacts print quality (labels with small fonts/graphics often need 300 dpi).
✅ Media Thickness Support
Standard vs thick media heads → some heads are optimized for thicker tags or heavy label stock.
These thicker media heads have slightly different gap and pressure parameters and are marked with -910 in the part number.
✅ Mechanical / Design Variation
Some parts, like 1-010045-900, represent slight physical variants (centered position or alternate fit) that match mechanical differences in the printer's media path.
📌 Summary Table
| Part Number | DPI | Media Type/Notes | Use Case |
|---|---|---|---|
| 1-010043-900 | 203 dpi | Standard printhead | Standard media |
| 1-010044-900 | 300 dpi | Standard printhead | High-resolution printing |
| 1-010043-910 | 203 dpi | Thick-media optimized | Heavy tags/labels |
| 1-010044-910 | 300 dpi | Thick-media optimized | High-detail on thick media |
| 1-010045-900 | 203 dpi | Offset/center variant | Mechanical alignment variant |


📍 Practical Buying Advice
Always match the DPI of the head to what the printer is configured for (203 dpi vs 300 dpi).
If you often run thicker tags or heavy labels, consider the -910 variants to ensure longer head life and better performance.
Use the exact OEM part number when ordering to avoid fit problems or unintended print quality issues.
