A media sensor system delivers greater flexibility for diverse media and applications. A head-open switch initiates auto-calibration for more precise printing. Multiple communication interfaces include parallel (CP-2140), RS-232, USB, and optional Ethernet(CP-2140E).The CP-2140 prints at 203dpi resolution and a speed of 4ips. Standard memory includes 4MB Flash and 8MB SDRAM. The printer has a modular design for easy maintenance, and printing noise is minimal. It supports the Windows 7 OS, 1DGS1 Data bar, 2DComposite codes, QR barcodes, and Windows TrueType fonts.
