Our engineering department

Located in our manufacturing plant in Botevgrad, Bulgaria, our engineering department is responsible for the industrialization, productization, and sustainment of APS thermal printing technologies developed by R&D. Engineering converts validated concepts into robust, manufacturable, and cost-optimized thermal printing mechanisms and printer platforms.

1. Mechanism engineering

Engineering owns the detailed design, integration, and release of thermal printing components, including:

Thermal printhead integration, covering mechanical mounting, thermal interfaces, and electrical interconnects.
Printing mechanism design, including platen rollers, head-loading mechanisms, frames, springs, and compliance systems.
Tolerance stack-up and pressure distribution control to ensure consistent dot formation across media widths.
Design verification and qualification against functional and environmental requirements.

2. Manufacturing & process engineering

Engineering defines and maintains production-ready processes, including:

Assembly process development for printheads, mechanisms, and subassemblies.
Tooling, jigs, and fixtures to ensure alignment, repeatability, and throughput.
Process capability analysis (Cp/Cpk) and yield optimization.
Manufacturing documentation, including work instructions, control plans, and process failure mode and effects analysis (PFMEAs).

3. Electrical & firmware engineering

Engineering delivers production-grade electronics and firmware, including:

Printhead drive boards and power distribution design.
Firmware implementation of strobe timing, energy control, and thermal compensation algorithms.
EMC/ESD compliance and safety certification support.
Hardware–software integration testing and regression control.

4. Supplier & cost engineering

The department manages supplier-facing technical execution, including:

Component specification and qualification (printheads, rollers, motors, sensors…).
Cost-down initiatives through design optimization and alternative sourcing.
Supplier process audits and technical change management.
Second-source and lifecycle risk mitigation.
