PT340/PT341 Series printers are ideal for busy, time-critical and customer-focused environments, such as retail and hospitality.

They’re also highly adaptable where space is at a premium: not only do they have a small footprint, they can be positioned either horizontally or vertically, even wall-mounted.

Both models have a recess under the case to neatly conceal interface connectors, and the PT341 has its own built-in power supply.

Flexible and versatile POS printing. PT340/PT341 Series printers can handle a variety of media types and sizes, including the industry standard 83mm-OD roll. They're perfect for receipts, coupons and tickets.

Both models deliver up to 300mm/sec print speed2 with up to 203 dpi resolution. They give you a choice of fonts and a variety of barcodes, including 2-dimensional QR codes. In addition, their internal memory can store up 576 KB, so you can add graphics and logos to your printout.

Save paper. And money, too. With PT340/PT341 Series printers, you can reduce the amount of paper you use for receipts—and reduce your costs, as well as your carbon footprint. This can be done in two ways:
By back-feeding the paper after each receipt prints— the top section usually left blank—you can save up to 5.7% of the paper you use.3
By using the Windows® driver that allows you to shrink the vertical print size, you can slash receipt lengths by up to 50% without losing printed data.4

With their long list of features and capabilities, PT340/PT341 Series receipt printers are perfect for your business. And they’re backed by a 2-Year Advanced Overnight Exchange warranty and 24/7/365 live technical support.4
