Print head Printronix P220358-001 12 dots/mm (300 dpi) replacement for thermal line printers

Print head Printronix P220358-001 is a replacement thermal print head with 12 dots/mm (300 dpi) resolution for 4-inch printers. It supplies the thermal element that creates high-contrast text and precise barcodes in line-thermal printing applications. Designed to fit compatible Printronix models including the T6000e, the unit is intended for service, maintenance and hardware restoration tasks in industrial, logistics and retail environments. The print head features a plastic-mounted RFID-capable design suitable for systems that use RFID-enabled media.

Advantages

The print head delivers a consistent 300 dpi dot density that supports clear, readable text and sharp barcode printing. Its replacement design facilitates straightforward swap-out during routine maintenance, reducing printer downtime. The plastic-mounted form and RFID compatibility allow integration with media systems that require RFID functionality while maintaining reliable thermal transfer performance.

Suitable for

• Field and in-house service and maintenance of compatible thermal line printers
• Printing high-density text and barcode labels at 300 dpi resolution
• Production, warehousing and retail environments using 4-inch label formats
• Systems that require RFID-capable print heads and media handling

When it may not be suitable

This replacement print head is specific to thermal line printers that accept 4-inch, 300 dpi heads with plastic mounting and RFID capability; it will not be compatible with printers that require different physical sizes, resolutions, or mounting styles. It is not suitable for direct-thermal printing systems that do not use a replaceable thermal print head or for printers that require different electrical or connector interfaces.

Key specifications

• Resolution: 12 dots/mm (300 dpi)
• Width: 4 inch (suitable for 4-inch label formats)
• Technology: Thermal line print head
• Mounting material: Plastic housing
• RFID: Compatible with RFID-enabled media systems
• Intended use: Replacement for maintenance and hardware restoration

How to use

Power down the printer and follow the manufacturer’s service instructions for safe removal of the old print head. Handle the replacement unit by its non-sensitive plastic housing and avoid touching the thermal element surface. Align the print head into the carrier, secure connectors and mounts according to the printer’s guide, then power on and run a head alignment and test print. Verify print quality and barcode readability at 300 dpi before returning the printer to production.

What to consider before purchase

• Confirm physical compatibility with your printer model and that it accepts 4-inch, 300 dpi print heads
• Ensure electrical and connector interfaces match your printer’s requirements
• Verify whether your application requires RFID capability and that the head’s RFID compatibility meets your media and system
• Check service documentation for recommended replacement procedures and ESD precautions

Usage recommendations

Use appropriate ESD protection and clean media paths before installation. After replacement, perform a test-print and barcode verification at full resolution to confirm consistent dot density and reliable scan performance.
