High-speed line printing - thanks to a 24-pin print head and 487 characters per second capability
A 24-pin impact print head strikes an ink ribbon to form characters rapidly, enabling continuous line and page output at quoted throughput. Mechanical construction focuses on sustained operation rather than photographic detail.
Fast text and form printing reduces batch-job wait times, keeping routine reports and run sheets moving smoothly.
Wide-format output – with A3 support for larger documents
A3-compatible paper handling allows printing of sheets up to A3 size at the machine's native 360 x 180 dpi resolution. The result is single-sheet wide layouts without the need for stitching smaller pages together.
Printing spreadsheets, wide tables or larger invoices on one sheet saves handling and improves readability.
Legacy connectivity and compatibility - with parallel and USB 2.0 ports
Both parallel and USB 2.0 interfaces are provided to accommodate older host systems and straightforward USB connections. The print architecture focuses on stable, direct connections for continuous workflows.
