Check UEWB and SK on the bottom label

This guide is for the TSP100IV receipt model TSP143IV-UEWB. UE is the wired LAN/USB model; UEWB SK is a label model with another manual. Read the full bottom label.

ItemCheck

ItemCheck
WindowsStar Windows Software Full 3.11.0, 272MB, 23 July 2026. Explicitly names UEWB and Windows 11 64-bit/ARM64, excluding IoT Enterprise. A powered-off USB printer is absent from Devices and Printers.
macOSCUPS 4.13.1; 559KB, 9 October 2026. The vendor lists macOS 13/14/15/26/27 and TSP100IV series; this alone does not prove installation on every CPU.
LinuxCUPS 3.17.0; 617KB, 14 April 2026. Lists RHEL 9.5 64-bit, Ubuntu 16.04LTS 32-bit/24.04LTS 64-bit and Chrome OS V134; match the actual environment.
OPOS / JavaPOSOPOS is included in Star Windows Software and configured separately in its utility. JavaPOS is a separate POS-system driver. Keep firmware separate.

Official driver installation sequence

For Windows USB, install the driver before attaching the cable to the PC. Then connect/power on and select the resulting print queue. Installer payloads, signatures, firmware and runtime installation were not tested here.

Separate USB-C, USB-A, LAN and Bluetooth

ItemCheck
USB-CWindows/Mac/Linux PC printing data; it does not charge the host. Use a data cable.
USB-ACompatible Android communication/charging up to 1.5A and listed peripherals. Start Android, connect its cable, then power on the printer. USB hubs are unsupported.
LAN / WLANThey cannot operate together: a connected LAN cable takes priority. Disconnect that cable for WLAN use.
BluetoothMatch Bluetooth Information → Dev Name on the self-print. Pairing success is separate from creating the POS print queue.

Wired LAN priority

Bluetooth / virtual COM guide

Four thermal-roll loading checks

  1. Prepare a nominal 80mm roll, or 58mm with the fitted guide. Maximum roll diameter is 83mm.
  2. Normal loading uses power on for automatic feed/cut. Jam removal has a separate power-off procedure.
  3. Remove the old core; follow the drawing: paper feeds from below for horizontal use, above for vertical use.
  4. Pull the edge straight and close both cover sides. Remove the cut scrap; match application/driver width to the roll and guide.

Official loading directions and media specifications

Self-print starts with power on and the cover open

  1. Load paper and turn the rear power switch on.
  2. Open the cover. Hold FEED until POWER flashes blue, then release it.
  3. Close the cover: the printer resets and prints settings, then returns to normal status. This is not a factory-settings reset.
ItemCheck
Self-printChecks basic printer operation/settings without a computer.
Host sampleCommon check: if self-print works, compare one job through the actual queue, connection and app.
Loading feed/cutPrepares paper; it does not prove host printing or a wireless connection.

Official device self-print procedure

Wi-Fi failures and the Bluetooth COM queue

For WLAN, first check the disconnected LAN cable, correct SSID/security/key, same network and DHCP. SSID Fail, Security Type Fail and Security Key Fail on the diagnostic print identify different checks. For weak signal or no address, compare placement, obstacles and DHCP.

Official FAQ for wireless diagnostic results

For operational problems, select UEWB in Star Quick Setup Utility → Printer Operation Check → Wireless LAN Troubleshoot. This function specifies Bluetooth and location-service prerequisites. No settings or resets were performed here.

Wireless troubleshooting function

In Windows Bluetooth, the guide distinguishes successful pairing from a later Driver is unavailable message. Check the virtual COM in hardware properties and create a separate queue with Star Windows Software; the paired device name itself is not the application print destination. Read the New Pairing Permission OFF precautions before deleting an existing pairing.

UEWB receipt-printing troubleshooting

Use the UEWB tab: Power/Error (blue/red), Bluetooth (blue) and Network (green). The eight selected states below are not invented numeric error codes.

Eight states from the UEWB tab

ItemCheck
Power blue / error offNormal power state; not proof of a successful host job.
Power and error onCover open; load paper and close both sides.
Power off / red every 0.5sPaper out; load suitable stock.
Power off / red every 0.125sCutter error; follow the power-off jam/lock guidance below.
Blue every 0.5s / error offHot head; printing resumes after cooling.
Blue every 2s / error offHot board; printing resumes after cooling.
WLAN Network greenWith power blue: green on means linked, off means disconnected, every 0.125s means no IP. Check DHCP/signal.
Bluetooth blueShows iOS connection; on Android/others it appears only during Bluetooth printing/status queries. Off alone does not establish failed pairing.

Eight cause checks

ItemCheck
No printer powerCheck rear switch, both cable ends and outlet.
Blank / missing paperCheck thermal stock, coated face, orientation and cover closure.
Locked cover / cutterDo not force the cover or paper; use the linked lock procedure.
USB-only failureCheck PC USB-C versus supported Android USB-A, cable and installation order.
WLAN-only failureCheck wired priority, diagnostic print, SSID, DHCP and same-network membership.
Paired but no outputCompare virtual COM, the separate POS queue and the app destination.
Streaks / faint printCheck thermal stock and the different head/roller cleaning methods.
Self-print works / host failsCommon check: compare queue pause, port, OS and model, then use this UEWB driver guide

Paper jams, cutter lock and cleaning

Power off for jam removal. Never force a locked cover. The Cutter Lock guide first tries off/on; if still locked, follow its powered-off front-cover, knob and home-position diagrams. Do not touch the blade or guess a rotation direction. Contact the seller if the error persists.

Official cutter-lock diagrams

For cleaning, switch off and unplug. Let the hot head cool; carefully use an ethanol/isopropyl-alcohol swab on its thermal area and dry fully before power on. Turn the rubber roller under a soft dry cloth. Do not blow paper-holder dust into the printer. No fixed cooling time or alcohol concentration is inferred.

Official evidence and scope

Checked 24 October 2026 against official product/support/download pages and the receipt manual naming UEWB. The UEWB indicator tab and selected connection/self-print screens were inspected in a browser. Installer payloads, archives, signatures, a physical printer, network changes and firmware updates were not tested.
