YJJ LTP02-245-13 2-Inch 58mm Ultra-Thin Thermal Printer Core for Handheld Portable POS Machines

Product Description:

YJJ LTP02-245-13 2-Inch 58mm Ultra-Thin Thermal Printer Core for Handheld Portable POS Machines

Features:

I. Basic Model Information

Model: LTP02-245-13

Type: Row-type thermal printer core (ultra-thin small 2-inch model)

Suffix distinction: Version 13 has no pressure paper shaft open cover detection switch; only the standard version lacks paper shortage photoelectric sensor + print head thermal resistance temperature measurement; the same series LTP01 is a thick model with a large volume, LTP02 focuses on lightness and portability

II. Printing Core Specifications

Printing method: Thermal dot matrix row printing

Single row dot count: 384 dots / row

Resolution: Horizontal 8 dots/mm (203 DPI), vertical 16 dots/mm

Pitch: Horizontal 0.125mm, vertical 0.0625mm

Paper width: Standard 58mm (compatible with 57.5±0.5mm thermal paper)

Effective printing width: 48mm

Paper thickness: 60~80μm common thermal paper

Maximum printing speed: 100mm/s (industry high-speed model of the same size)

Maximum synchronous heating points: 45 points (lower power consumption compared to LTP01)

Paper feeding structure: Straight paper feeding, simple paper feeding mechanism, compact structure

III. Built-in Detection Sensors

Print head temperature measurement: Built-in NTC thermal resistor, overheat protection

Paper shortage detection: Reflective photoelectric sensor

Paper shaft open cover detection: None (core difference of version 13)

IV. Electrical Power Supply Parameters (Dual Independent Power Supply)

1. Voltage range

Heating / motor drive voltage Vp: 5.5 ~ 9.5V DC

Logic control voltage Vdd: 3.0 ~ 3.6V DC (typical 3.3V)

2. Peak current

Print head peak current: 2.64A (9.5V, simultaneous heating of 45 points)

Stepper motor maximum current: 0.6A

Logic standby current: ≤100mA

3. Print head thermal resistance: 162~198Ω (typical 180Ω@25℃)

4. Wiring: 30Pin FPC flexible wiring

V. Lifespan and Environmental Operating Conditions Service life

Heating pulse life: ≥ 1 billion times

Paper path wear life: ≥ 50 km (original factory standard thermal paper)

Operating environment: -10℃ ~ +50℃, 20% ~ 85% RH (no condensation)

Storage environment: -20℃ ~ +60℃, no condensation

VI. Physical dimensions and weight

Overall dimensions (excluding motor / wiring protrusions): 67.3 × 18.1 × 30.0 mm

Net weight of the entire machine: approximately 28g (about 40% lighter than LTP01-245, ultra-thin and lightweight)

VII. Core advantages comparison LTP01-245-C1

Thickness only 18.1mm, significantly reduced volume, suitable for handheld portable devices

Overall weight 28g, lightweight, preferred choice for battery-powered equipment

Number of synchronous hotspots 45 points, lower peak current, lower power design cost

Highest printing speed 100mm/s, faster than 75mm/s of LTP01

Shortcomings: Compact internal structure, not suitable for continuous long-term industrial printing with large rolls of paper

VIII. Applicable devices

Handheld portable POS machines, medical analyzers, portable recorders, handheld detectors, vehicle ticket terminals, small handheld financial terminals, industrial portable collection equipment
