The Epson SureColor SC-T3130N is a 24-inch wireless CAD/technical printer with a PrecisionCore TFP head and UltraChrome XD2 pigment ink — A1 prints in about 34 seconds at 2400x1200 dpi. Auto sheet feeder handles cut media, and the unit takes both roll and sheet. The thing buyers regret is choosing the cartridge-based T3130N when the CISS-based T3130X would have saved them real money over a few years. Run the math: estimate annual D-size volume, compare ink cost per print between the two. For low-to-moderate volume, the T3130N is fine and cheaper upfront. For high daily volume, pay the upcharge for the X-model with bottle refills. Same physical printer otherwise. Pigment ink survives jobsite conditions. Wi-Fi and Wi-Fi Direct mean a single architect can print without involving IT, and Ethernet handles shared use. The 4.3-inch touchscreen handles job control without a desktop client. Plan an optional stand if you don't have desk depth for a 24-inch unit.
