The TSC PEX-1121 from the PEX-1001 Series is an enterprise-level 4-inch print engine for label applicators and print-and-apply lines. Its die-cast construction is bolt-compatible with mainstream applicators, and the commonly used GPIO interface supports mainstream applicator emulations for fast integration. It prints in thermal transfer and direct thermal at 203 dpi and up to 457 mm/s – superior speed in its class – registers labels as small as 5 mm and uses 600 m ribbons; GPIO (DB15F) + parallel, USB, RS-232, Ethernet and a USB host port are standard. This version, PEX-1121-A001-0002, is the left-hand (LH) version – choose the orientation that matches the media path of your applicator.
📦 What's in the box – PEX-1121-A001-0002

- ✅ Setup guide – printed quick start guide
- ❌ Labels – NOT included
- ❌ Thermal transfer ribbon – NOT included
- ❌ Ethernet (LAN) cable – NOT included
- ❌ Label applicator, mounting hardware and GPIO cable – NOT included (the print engine is installed in your applicator)
✅ Ready to integrate – the power supply is built in, and the power cord and USB cable are included for set-up and testing; you only need labels, a thermal transfer ribbon (direct thermal labels print without one) and the GPIO connection to your applicator. For a network connection, use the built-in Ethernet port with a standard RJ45 patch cable (not included).
💡 Useful extras: labels on 76 mm cores for your applicator's unwinder (TSC 38-T102102-10LF or Zebra 76180); ribbons up to 600 m (TSC P159049-001 or TSC P159079-001); upgrade kits and spare parts: spare printhead (TSC PH-PEX-1001-0001).
Key Features
- Bolt-compatible design – robust die-cast construction that fits mainstream applicators, with a commonly used GPIO interface and applicator emulations for drop-in replacement.
- Left-hand and right-hand versions – mirror-image models for either side of the applicator; this unit is the left-hand version (LH).
- Thermal transfer and direct thermal – up to 457 mm/s at 203 dpi with a maximum print width of 104 mm.
- High-precision registration – labels as small as 5 mm, an adjustable gap sensor and a switchable top or bottom black-mark sensor.
- Robust peel-off – state-of-the-art peel-off capability for reliable label dispensing in print-and-apply operation.
- Flexible media – media 20–114 mm wide and 0.076–0.305 mm thick; continuous, die-cut, black-mark, notched and fanfold media fed from the applicator's unwinder.
- 600 m ribbons – long ribbons (1-inch core, ink coated inside or outside) mean fewer changes on busy lines.
- Multi-connectivity – GPIO (DB15F) + Centronics parallel, USB 2.0, RS-232, 10/100 Ethernet and a front USB host port; dealer options: DB25F GPIO and a Wi-Fi 802.11ac + Bluetooth 4.2 combo module.
- 3.5-inch colour display – 320 × 240 colour TFT with six buttons and a status indicator for quick set-up.
- Easy replacement of other brands – TSPL-EZD with EPL, ZPL, ZPL II and DPL compatibility runs existing label formats unchanged.
- TSC Sense Care and remote management – automatic detection of printhead bad dots during printing, plus SOTI Connect (via Ethernet or Wi-Fi) and TSC Console.
- Easy maintenance – a rear drawer gives quick access to maintenance parts, and the modular media drive system is quick and easy to replace.
Ideal Applications
- Print and apply – automatic labelling of cartons, cases and products on packaging lines
- Transport and logistics – pallet labelling and carton shipping labels
- Manufacturing – automotive, food and beverage product identification
- Healthcare – pharmaceutical labelling
