Executive Summary
When it comes to back label numbering, sequence integrity and uptime are everything. The TeslaJet NP45 provides the simplicity and compactness of cartridge-based thermal inkjet technology without sacrificing industrial-grade reliability. Based on the globally trusted HP 45a 0.5" printhead technology, this highly modular system mounts easily onto existing web presses, rewinders, or finishing lines. Whether you are printing simple batch codes, sequential numbers, or variable barcodes on the back of label liners, the NP45 delivers clean, 600 dpi print quality with unmatched ease of use.
Key Advantages
Compact Web Integration: The low-profile printhead design mounts easily into tight spaces on existing label rewinders and continuous web lines.
Zero-Mess Maintenance: Snap-in disposable HP cartridges provide clean operation with no complex cleaning routines or fluid pumps, maximizing line uptime.
Ultimate Substrate Flexibility: Print on almost any label liner. Swap cartridges to switch between aqueous inks for porous paper liners and solvent inks for coated or poly-backed liners.
Modular Configurations: Available in print widths of 0.5", 1.0", 1.5", 2.0", 4.0", or fully custom setups to match your specific web width and numbering requirements.
Cost-Effective Scaling: Entry-level pricing combined with disposable or bulk ink delivery drastically lowers both initial capital expenditure and ongoing maintenance costs per code.

Frequently Asked Questions
How is the NP45 different from a standard inkjet for label numbering?
The NP45 uses HP 45a cartridge technology where the printhead is built into the ink cartridge itself. Every cartridge swap delivers a fresh printhead, eliminating the gradual print quality degradation that plagues traditional fixed-head systems on long sequential numbering runs.
Can the NP45 mount on my existing label rewinder?
Yes. The NP45's low-profile printhead is specifically designed for tight integration with continuous web equipment. It mounts on existing label rewinders, presses, and finishing lines without major retrofitting.
What inks work on poly-backed label liners?
The NP45 supports both aqueous inks (for porous paper liners) and solvent inks (for poly-coated and plastic liner backings). Cartridges swap in seconds, letting you handle multiple label types on the same equipment without flushing or downtime.
