The DC3R1 runs at 230 mm\/s with USB + LAN. The DC3R3 runs at 260 mm\/s and adds a serial port, giving USB + LAN + RS232. Both print 72 mm wide at 576 dots per line, both carry an auto-cutter, and both drive a cash drawer at DC 24V\/1A — so the till pops open the moment the bill prints.\u003c\/p\u003e\n\u003cp\u003eThese are counter printers for Indian businesses that have outgrown a basic USB machine: supermarkets, restaurants and QSR chains, wholesale counters, pharmacies, hotels and petrol pumps.

Networking means your billing PC can sit anywhere and a second terminal can share the same printer — which is what actually happens as a shop grows from one counter to two. The drawer port opens the till on print without a separate trigger, and that one detail speeds up every cash transaction of the day.\u003c\/p\u003e\n\u003cp\u003eBetween the two variants the difference is small, and worth stating plainly: the DC3R3 is 30 mm\/s faster and adds RS232. If nothing in your setup is serial, the DC3R1 does the same job for less. Note the operating range tops out at 45°C, so an unshaded counter through a north Indian summer needs shade or a fan.
