Model and driver source
Receipt UE, wireless UEWB and label SK are different
Check the bottom model label and use the receipt-printer manual. UE has USB and wired LAN; built-in Wi-Fi/Bluetooth belongs to UEWB. SK is the label model. External communication accessories require their own compatibility checks. The product table lists thermal receipts up to 250mm/s, nominal 80mm or guided 58mm rolls and a partial cutter; ink cartridges and ribbons are not used.
Choose the package for your OS and POS connection
Checked 2026-10-12: Star Windows Software Full 3.11.0, 272MB, updated 2026-07-23, explicitly includes TSP143IV-UE and lists Windows11 64-bit/ARM64 except IoT Enterprise. Full includes manuals; the separate EXE omits them. The page notes that a powered-off USB printer disappears from Devices and Printers. These are vendor-listed conditions, not an installation guarantee.
macOS CUPS 4.13.1, 559KB, updated 2026-10-09, lists macOS13/14/15/26/27 and TSP100IV series; those are the manufacturer’s labels. Linux CUPS 3.17.0, 617KB, updated 2026-04-14, lists TSP100IV and environments including RHEL9.5 64-bit and Ubuntu24.04LTS 64-bit. Check the actual OS/CPU and software manual. OPOS and JavaPOS setup is separate POS integration; OPOS is included in Star Windows Software. Do not substitute a firmware update for a printing driver.
Use USB-C for the computer; USB-A has another role
The exact USB connection guide routes Windows/Mac/Linux printing to the printer USB-C port, which communicates but does not charge the host. USB-A supports compatible Android communication/charging up to 1.5A and listed peripherals. For Android communication, start the Android device, connect its cable, then switch the printer on. USB-A hubs are unsupported; a charging-only connection is not proof of printing connectivity. iPhone/iPad USB printing is unsupported here; use the supported network route.
Windows USB installation requires the driver to finish installing before the printer USB cable is plugged into the computer. Then power the printer on and connect USB to create the queue via plug-and-play. Select that exact queue for a Windows test page. Follow the installer’s own prompts and current package requirements; this site has not run the installer.
TSP143IV-UE receipt printing: device and host
Self-print starts with power on and the cover open
Load suitable paper. Switch the rear power switch on, open the cover, and hold FEED until the power LED flashes blue; release FEED, then close the cover. The printer resets and prints its settings without a computer. It resets back to normal status after completion. This is the exact self-print sequence, not a hold-FEED-while-powering-on recipe or factory-settings reset.
Eight selected LED groups
Use the UE tab of the official LED table: blue Power, red Error, green Network. UEWB uses different controls. Eight selected groups below include normal/USB notifications; they are not eight invented numeric codes.
| LED group | Meaning | Guide |
|---|---|---|
| Blue power on; red error off | Ready state; compare a device-only print. | Check |
| Blue/red flash for about5s | Together: charging-only device. Alternating: USB-A hub. | Check |
| Blue flashes; red off | 0.5s: hot head. 2s: hot board. Cooling resumes output. | Check |
| Blue and red stay on | Cover open. | Check |
| Blue off; red flashes0.5s | Paper exhausted. | Check |
| Blue off; red flashes0.125s | Cutter fault. | Check |
| Blue on; green network off | Wired link disconnected. | Check |
| Blue on; green flashes0.125s | IP address unavailable. | Check |
Eight model-specific cause checks
| Symptom | First check | Guide |
|---|---|---|
| No lights or output | Check the power cord ends, socket and rear switch. | Power |
| Blank receipt / faint print | Thermal paper, loading direction and cooled head inspection. | Paper |
| Red cover / paper indication | Close both cover sides; replenish a suitable roll. | Paper |
| Cutter error / cover locked | Power off; follow jam/lock diagrams, never force the cover. | Cutter |
| USB connected but not printing | Correct USB-C port, data cable and USB-A role; no hub. | USB |
| LAN offline / no IP | Physical link, current self-print address and DHCP. | LAN |
| 58mm output clipped / reduced | Match fitted guide, actual roll and POS/driver paper width. | Width |
| Self-print works; PC/POS fails | Common checks: exact queue/port, pause, model/OS package and POS driver. | Driver |
Read the current address before changing a port
The wired-LAN guide identifies IP Address under Current IP Parameters Status on the self-print. Compare it with the selected computer/POS printer port. Green off indicates cable/link; green0.125s blinking indicates address acquisition. Check the DHCP server or administrator-assigned static address. Use the same network segment; do not guess an unused static address or start with communication reset.
Thermal paper and loading direction
The paper guide specifies nominal80mm or58mm with the fitted guide, maximum roll diameter83mm. Horizontal and vertical loading directions differ: follow the matching drawing, pull the edge straight and close both cover sides. Normal loading uses power on for automatic feed/cut; jam removal uses power off. Ordinary paper, old thermal stock or the wrong coated face can cause blank/faint output.
Match the physical width and printing settings
Fit the58mm guide when using the narrow roll and align POS/driver width with the actual paper. Compare a small test receipt and the device-only output before changing margins or reinstalling. These application/driver comparisons are common checks; UE does not become an SK label printer by selecting another paper size.
Power off for paper removal; do not force a locked cover
Jam removal calls for power off and clearing all fragments from the holder/outlet. If the cover is locked, the cutter-lock guide first uses power off/on to release it automatically. If that fails, its front-cover/knob/Home-position procedure is performed with power off; never touch the blade, pull trapped paper hard or force the cover. Follow the drawings or ask the seller; persistent cutter faults need service.
Cooling and targeted cleaning have different steps
With red error off, blue0.5s/2s blinking indicates hot head/board respectively; allow automatic cooling. For interior maintenance, switch off and unplug, let the head cool, and follow its specified head cotton-swab/alcohol procedure. Roller cleaning uses a soft dry cloth. Avoid scratches/static damage and air blown into the holder; power on only when alcohol has dried completely. Persistent thermistor or memory faults require the seller, not repeated driver installs.
Check the rear switch and mains connection
If the power LED is off, verify the cord, socket and rear switch. Record repeat fault patterns and contact the seller if normal restart does not clear them; this selected table is not every hardware fault. Do not open internal power electronics.
