Integrating a retail-hardened PC directly into a desktop receipt printer, the Epson C31CC74542 runs on a 1.86 GHz processor paired with 6 GB of DDR3 SDRAM and a 16 GB solid-state drive, making it a self-contained POS unit rather than a printer that requires an external computer. Direct thermal printing delivers monochrome receipts at up to 11.81 in/s at 180 x 180 dpi across a 2.83-inch print width, accepting roll paper up to 3.15 inches wide, 3.15 mil thick, and 3.27 inches in maximum roll diameter. Connectivity covers Fast Ethernet, USB, USB host, serial and VGA ports, supporting Mac and PC platforms. Operating at 24 V DC via power adapter, the unit measures 5.7 in wide by 7.7 in deep by 5.8 in tall and weighs 3.50 lb. Barcode support spans UPC-A, UPC-E, Code 128, Code 39, EAN-13, PDF-417, QR Code and GS1 DataBar families. FCC, ICES-003 Class A, TUV (EN60950-1) and Energy Star qualified, the C31CC74542 carries a 3-year limited warranty.
