TSP143IV: choose the full model
Read the full bottom label, then use the four-model chooser to open the matching guide.
- Match the full model number on the device label, including suffixes.
- Check your operating-system version and architecture on the official support page.
- Cancel pending print jobs before replacing an existing driver.
- Follow the manufacturer’s instructions for power, USB, and network connections.
Identify your model before installation
Read the full label on the bottom
TSP143IV by itself is a starting point for choosing a model. The official model-label page separates the TSP100IV receipt product from TSP100IV SK label products and lists four interface variants. Models in the same series can require different driver choices, LED interpretation and cutter checks.
| Full model / connections | Next guide |
|---|---|
| TSP143IV-UEReceipt printer: USB and wired LAN. | UE driver guide Official manual |
| TSP143IV-UEWBReceipt printer: USB, wired LAN, wireless LAN and Bluetooth. | UEWB receipt guide Official manual |
| TSP143IV-UE SKLabel printer: USB and wired LAN. | UE SK official manual SK official support |
| TSP143IV-UEWB SKLabel printer: USB, wired LAN, wireless LAN and Bluetooth. | UEWB SK label guide Official manual |
UEWB has built-in wireless LAN/Bluetooth; the receipt UE product description specifies USB/LAN. Optional accessories need separate compatibility checks. The SK manual describes linerless sticky labels and also receipt paper: paper use alone does not identify the hardware. Do not infer a model from the front series name or X4 marketing label alone.
Choose the model before choosing a package
The download button opens the official TSP100IV support page. Match the full label, operating system, version, CPU and POS application before selecting Windows print software, OPOS/JavaPOS or CUPS. Availability and supported architectures belong to the exact package; this family guide does not promise that every package supports every variant. Firmware and mobile utilities are different components.
Choose a guide in the table only when the entire bottom label matches. UE and UEWB guides cover receipt printers; UEWB SK has its own sticky-label guide. Do not apply UEWB wireless steps to UE, or receipt-model LED/cutter instructions to SK. For UE SK, use the official SK manual and support page above.

Start with the connection actually fitted
Identify the rear connector and the matching section of the exact model manual. A wired-LAN UE is not made wireless by reinstalling a driver. Follow the selected installer’s USB connection order; for network printing, compare the printer’s actual current address with the PC/POS port. Do not factory-reset communications or substitute another model’s software as a first step.
Common checks until the model is identified
The following six groups are a triage sequence, not six model-specific error codes. Exact LEDs, self-print buttons, paper, cutters and reset steps come from the selected model manual. A driver cause returns to this page’s model-aware download panel; confirmed UE users can continue to its exact guide.
| Possible cause | First check | Guide |
|---|---|---|
| Wrong suffix or product | Read the bottom label, including UE/UEWB and SK, before selecting a guide. | Choose model |
| Device will not print by itself | Record the exact lights/message. Follow that variant’s manual for its supported test and paper/cutter checks. | Exact manual |
| USB cable or wrong connector | Compare connector, cable and installer order with the selected model manual. | Common USB checks |
| Offline or network address | Check only fitted interfaces, current address, cable/link and the selected queue’s port. | Common offline checks |
| Queue or POS print failure | If the model-specific device test works, compare queue pause, job, port and application driver choice. | Common queue checks |
| Model, driver or OS mismatch | Connection/device checks can narrow the problem; they do not prove a missing driver. Select the exact model and package. | Driver selection |

Guide routing checked 28 October 2026 against the official bottom-label table, separate receipt/SK manuals and support pages. Existing UE, UEWB and UEWB SK guides now open directly. UE SK stays on official sources rather than another variant’s guide. Each guide retains its own OS, LED and cutter evidence and verification dates.
