Unlike dot matrix printers, the versatile GP-C831 can print advanced barcodes, crisp text and photographs, and can be used with a variety of media, including glossy paper and labels. Whatever the media used, Epson's DURABrite Ultra pigment ink yields long-lasting prints that resist water, fading, smudging and highlighter pens. The GP-C831 has a durable build and is designed to provide up to five years of high-volume, high-performance printing. Patented Epson technology protects the printhead nozzles from dust, making the GP-C831 suitable for demanding environments. Helping to improve efficiency, the GP-C831 prints up to 19.7 pages per minute in super draft mode, and clears paper jams in seconds by automatically releasing the paper if an error occurs. This is backed up by a push-button manual paper release. The GP-C831 comes with parallel, USB and LAN 100/10BASE interfaces as standard to make integration easy.
