A 400 million-character printhead life anchors the Epson C11C558001, a 24-pin dot matrix impact printer built for sustained throughput in point-of-sale, manufacturing, and production environments. It prints bi-directionally at up to 529 cps across 80 columns, with a paper feed speed of 45 milliseconds per 1/6 in and 5 in per second continuous feed. Multipart forms run to an original plus 4 carbonless copies at a maximum thickness of 0.018 in, with single-sheet widths from 3.9 in to 10.1 in and continuous widths from 4.0 in to 10.0 in. Parallel and USB interfaces are standard, and 128 KB of memory supports Epson ESC/P2 and IBM PPDS emulation alongside 11 resident bar code fonts including Code 39, Code 128, EAN-13, and POSTNET. The 20,000-hour MTBF rating reflects long-cycle reliability, and the 15.60 lb chassis measures 16.3 in wide by 13.8 in deep by 6.3 in tall, running on 110 V AC at 60 Hz.
