Star Micronics 39900312 Print Head Assembly for DP1401R Direct Thermal Printers
Overview
The Star Micronics 39900312 is a genuine replacement print head assembly designed for the DP1401R direct thermal label printer. Each order includes a quantity of 20 print head assemblies — a multi-unit pack sized for service depots, facilities teams, and high-volume print environments where maintaining spare components on-site reduces unplanned downtime. The DP1401R supports both standard label and linerless media formats, and this print head is the correct consumable replacement to maintain print quality across both media types.
Direct thermal print heads degrade over time from heat cycling and media abrasion. Stocking the 39900312 in bulk means a technician can swap a worn head and return a printer to service in minutes rather than waiting on a parts order. At 0.01 lb per assembly, these ship and store easily alongside other printer consumables.
Key Features
- Compatible with Linerless Media: The DP1401R handles linerless label stock, which eliminates liner waste and reduces media costs — this print head maintains that capability through the replacement cycle.
- Direct Thermal Print Method: No ink, toner, or ribbon to manage. The print head applies heat directly to thermal media, so replacement intervals are driven by head wear and media volume, not consumable supply chains.
- 20-Unit Pack Quantity: Sized for service organizations and multi-site deployments. Buying in quantity of 20 reduces per-unit cost and keeps your maintenance inventory covered without repeated reorder cycles.
- 2-Year Warranty: Each assembly carries a 2-year manufacturer warranty, providing coverage against defects through a standard service cycle.
- Manufactured in the United States: Domestic origin supports procurement programs with US-sourcing requirements.

The Star Micronics 39900312 is a purpose-specific replacement part — the right call for service teams running DP1401R printers at volume. The 20-unit pack format is what matters operationally here: rather than sourcing a single head reactively when a printer goes down, a depot or facilities team stocks the 39900312 in advance and keeps mean time to repair under an hour. That's the actual value proposition for a part at this weight class (0.01 lb per assembly).
Technical Highlights:
- Linerless Media Compatibility: Linerless printing eliminates backing paper waste and can reduce media costs in high-throughput label environments — this head maintains that capability through the replacement cycle on the DP1401R.
- Direct Thermal Architecture: No ribbon or ink cartridge interaction at the head level means replacement is straightforward — wear is driven purely by thermal cycling and abrasive media contact, making service intervals predictable.
- 20-Unit Pack: For a multi-site or depot scenario, bulk stocking at this quantity avoids repeated small-order logistics and keeps per-unit cost down across a printer fleet.
Deployment Considerations:
- Verify the DP1401R firmware and head spec revision before ordering in bulk — confirm the 39900312 matches the specific DP1401R variant in your environment to avoid a mismatch on a 20-unit purchase.
- Direct thermal heads are sensitive to media quality; using non-spec linerless stock will accelerate wear and shorten the service interval regardless of part authenticity.
Best fit for logistics hubs, retail back-office environments, or any operation running a fleet of DP1401R printers where planned preventive maintenance — rather than reactive repair — drives service scheduling.
