Model and driver source
Use the SK manual for the full UEWB SK label
Check the bottom label: this is the USB, wired-LAN, wireless-LAN and Bluetooth SK model. Receipt UE/UEWB and wired-only UE SK have different identities. The exact SK manual identifies UEWB SK and explicitly supports linerless sticky labels and receipt paper. A roll of receipt paper does not turn SK hardware into a receipt UE model.
Choose the component and current package requirements
Checked2026-10-12: the SK support listing has Windows, macOS and Linux components. Star Windows Software Full3.11.0 (272MB, updated2026-07-23) explicitly lists TSP143IV-UEWB SK and Windows11 64-bit/ARM64 except IoT Enterprise. Its USB printer is absent from Devices and Printers when powered off. These are vendor conditions, not an installation test.
The SK installation manual requires the Windows driver before connecting USB; then the exact queue is created through plug-and-play. OPOS is included in Star Windows Software; JavaPOS and macOS CUPS / Linux CUPS serve different applications. Follow each package’s OS/CPU/software manual; the older broad Windows10/macOS11–26 summary is not a promise for every current package. Firmware is separate from the print driver.
Choose a Mac or Linux CUPS file by its own OS list
Checked 2026-10-15: the exact SK support page links the three CUPS entries below. The SK installation manual distinguishes CUPS for Mac/Linux printing from JavaPOS for a POS application or system that uses JavaPOS. Match the complete UEWB SK identity and application requirement before choosing the software.
| Official item | Version / page update / listed size | Listed platform scope |
|---|---|---|
| Linux CUPS | 3.17.0 / 14 April 2026 / 617KB | RHEL9.5 (64bit); Ubuntu16.04LTS (32bit) or24.04LTS (64bit); Chrome OS V134. |
| macOS CUPS | 4.13.1 / 9 October 2026 / 559KB | macOS13,14,15,26; the manufacturer also lists27. |
| macOS CUPS V4.13.0 | 4.13.0 / 9 October 2026 / 928KB | macOS11–15 and OS X10.14/10.15. Its OS list differs from4.13.1. |
For example, macOS11/12 appears in the4.13.0 entry, not the observed4.13.1 list. Do not copy one entry’s OS range onto the other or choose only by the higher version number. Linux32/64-bit labels do not establish ARM/Raspberry Pi support; the listed pages do not by themselves verify Intel/Apple Silicon/Rosetta, all distribution builds or CUPS versions. The macOS27 field is recorded as Star’s listing, not an independently tested OS-release or runtime claim.
- Compare the exact SK model, actual OS and application requirements with the same-model driver download guide.
- Use the OS-specific software manual linked by the SK installation page. The Linux CUPS Software Manual listing is version8.0, updated14April2026; this is a document version, separate from driver3.17.0. The 15 October check read listing metadata only; the separate 17 October PDF review below covers exact SK queue and Hold Print conditions.
- Read the manufacturer’s license and installation conditions yourself. Preserve current queue/port and jobs. Compare the existing SK self-print and eight cause checks before blaming software; label-removal waiting can be expected device behavior.
This increment verifies public listings and exact-model role mapping. No license was accepted, archive downloaded, installer run or physical output tested. Earlier12October Windows3.11.0 and hardware/hold-sensor/eight-cause guidance retain their dates; the unresolved unique LED mapping remains excluded.
Linux queue selection and Hold Print waiting
Checked 2026-10-17: the official Linux PDF is Rev.8.0 (May 2025 history), matching the manual listing. Document 8.0 and driver 3.17.0 are separate versions.
- The exact UEWB SK row requires firmware 3.0+ (p.5). Compare the existing self-print; this is not an instruction to update firmware.
- Select Star TSP100 Cutter (en) for USB, Ethernet or Bluetooth (pp.13/17/22), using your actual connection. The pictured MCP31 queue and example IP are not SK settings to copy.
Taken Sensor Control → Hold Print
Enable is the documented default: the next job waits until the printed label leaves the exit (p.38). Remove the finished label before reinstalling a driver; compare the SK hold-sensor check.
This CUPS software excludes ESC/POS emulation (p.4). Package CPU/signatures and current runtime remain untested. For missing driver files, use this model’s driver download guide. Existing LED limitations remain unchanged.
Self-print with power already on and cover open
Load suitable stock first. Turn on the rear switch, open the cover, hold FEED until the power indication flashes blue, release it, then close the cover. Settings print without a computer; a normal reset returns the printer to status display. Remove the printed stock. The SK self-print procedure is not a power-on FEED shortcut or factory-default reset. Do not add repeated long presses: the hold-sensor setting mode uses additional FEED actions.
Labels and receipts have different stock rules
The SK stock table lists linerless labels79.5±0.5 /57.5±0.5 /39.0±0.5mm, thickness65–98μm, and receipts79.5±0.5 /57.5±0.5mm, thickness49–85μm. Maximum roll diameter is83mm. Nominal58mm and40mm label rolls need the paper guide; receipt stock has no40mm entry. Match the actual stock and POS/driver width rather than treating every paper type alike.
Normal loading is powered: remove the old core, tighten a loose roll as illustrated, pull the end straight, close both sides and remove the automatically cut piece. Vertical use is label-stock only. The manufacturer does not recommend switching between label and receipt rolls during operation. Follow the orientation diagram; do not use a different label construction merely because its width fits.
Roll guides and printing width at first setup
Fit the 58 mm or 40 mm roll guides at setup
Choose the width before putting the printer into service. 58 mm is available for labels and receipts. 40 mm is for linerless labels. Star warns that changing widths after use can cause printing or cutting problems because the contact area changes on the head, rollers and cutter.
- 58 mm roll. Match the guide’s tabs to the holes and grooves shown in the manual and press the guide into place until it clicks.
- 40 mm label roll. Fit guide B first along the right wall of the roll holder. Then align guide A with the holes and grooves shown in the diagram. Check that both guides click into place. Star’s roll guide diagrams
- Set the printer memory switch for Printing width to match the initial roll width. Star documents Star Quick Setup Utility on mobile and the settings utility in Star Windows Software. Star’s app guide
Load the roll and run the printer self-print to check feeding and cutting. If the self-print is correct but POS output is clipped or shifted, compare the job’s paper width and the selected queue as common host checks. See the driver guide for this exact model. Star’s roll specifications and loading steps
A waiting next label can be normal
The hold print sensor detects removal of the printed label at the exit. Enabled is the default and recommended setting: the next label waits until the previous label is taken. Remove that cut label first; do not pull it before cutting. Disabling the sensor can make labels stick together or to the printer/mounting surface, so it is not the first response to an apparently stalled queue. Settings involve both Hold Print Control and Hold Print Status; do not change only one.
When a 5 mm top margin becomes 11 mm
If the label prints but the top margin grows, check Hold Print and the paper exit. The official SK FAQ explains that with the sensor disabled, the printer uses 11 mm even if 5 mm was set when the next print starts with paper still at the exit, or when two or more sheets print continuously. This helps prevent jams.
Clear the exit once the output is fully cut. In Star Quick Setup Utility, open Change Printer Settings → Memory Switch Settings and check both Hold Print Control and Hold Print Status. With the default Enabled setting, the next print waits for the previous output to be removed. Compare the margin by printing the same layout one sheet at a time.
If the device self-print works but the PC never prints the first sheet, check the selected queue and port, then see this model’s driver guide.

Eight cause checks
| Possible cause | First check | Guide |
|---|---|---|
| Next label waits | Take the fully cut previous label; enabled hold sensor deliberately waits. | Hold sensor |
| Wrong paper or clipped layout | Check label versus receipt specs, guide, width and vertical label-only use. | Paper rules |
| Blank or faint output | Compare device-only self-print, thermal face and cooled-head maintenance before reinstalling. | Print quality |
| Adhesive jam or locked cover | Stop, power off, clear fragments/glue as specified; no force or blade contact. | Jam and cutter |
| USB connected but not printing | Use computer USB-C data; Android USB-A has another role. No USB-A hub. | USB roles |
| Network path changed | Wired LAN takes priority; WLAN cannot operate together with a fitted LAN cable. Compare actual IP and port. | LAN / WLAN |
| Bluetooth paired but Windows print fails | Pairing alone is not a print queue; check virtual COM and separate Star Windows Software queue. | Bluetooth queue |
| Device test works, PC/POS fails | Common host checks: exact queue, pause/job/port, supported package and POS component. | This model driver |
USB-C computer data and USB-A Android are separate
The exact SK USB instructions use USB-C for Windows/Mac/Linux communication only, with no device charging. Android uses USB-A communication/charging up to1.5A: start Android, connect its cable, then power the printer. Verify the actual Android/device setup. The SK USB hub notification says a USB-A hub cannot be used; charging by itself is not successful printing.
Compare the current address before a reset
UEWB SK wireless guidance states that a connected LAN cable takes priority and wired/wireless LAN cannot operate together. Choose the intended path with the administrator; wired setup uses the self-print’s Current IP Parameters Status / IP Address. Compare that actual address with the PC/POS port. Wireless diagnosis should show Successful and an allocated IP. Check the correct SSID/security and DHCP; do not erase communications as a routine first check.
When the UEWB SK wireless diagnosis says Failed
The printer automatically prints a Wireless Network Diagnosis report after setup. Successful with an assigned IP address confirms the wireless setup. If setup failed, check which line on the printout shows (Fail).
- SSID (Fail): the printer could not find that network. Check the exact name of the store’s network. If the access point is far away or there are obstacles, adjust the placement and try setup again. For Wi-Fi, also check when wired LAN takes priority.
- Security Type / Security Key (Fail): check the security settings. For Security Type, compare the access point’s security mode. Leaving a required key blank in the app can also produce this result. For Security Key, check the password for that Wi-Fi network.
- IP Address (Didn’t obtain): the printer did not get an address. If Signal Strength says (Weak), move closer to the access point or reduce obstacles. If the signal looks good and the printer still has no address, ask the network administrator to check DHCP and whether the access point has reached its device limit.
If an existing connection drops, turn on Bluetooth and location services on iOS or Android. Open Star Quick Setup Utility → Printer Operation Check → Wireless LAN Troubleshoot, select TSP143IV-UEWB as shown in the app, and bring the phone near the printer LED to see the diagnosis.
If the report says Successful and shows an IP address but PC or POS jobs fail, check that the host and printer are on the same network and compare the print port with the address on the report. See the UEWB SK driver guide for the print queue.

Windows pairing is separate from the printing queue
The UEWB SK Bluetooth manual checks Dev Name under Bluetooth Information on self-print. Windows can show Driver is unavailable after pairing; the manual still regards pairing as complete. Check its virtual COM port and create a separate Star Windows Software print queue. If New Pairing Permission is OFF, do not remove/forget an existing paired device as a first troubleshooting step: re-pairing is restricted.
Bluetooth connection indication depends on the host
Verified 19 October 2026: Bluetooth host-indication scope.
The UEWB SK LED manual separates hosts. For iOS, the connected indication means the host link is established. For other hosts, including Android, that indication is shown only while Bluetooth printing or status acquisition takes place. A dark indicator between jobs therefore does not by itself establish a failed pairing. Compare the device name on self-print and the host’s actual pairing and queue, then compare a small print or status check through the intended application. This is separate from the existing Windows virtual-COM and print-queue setup.

SK paper jam: four removal steps before reloading
Use the SK instructions for the full UEWB SK model on the bottom label.
- Use the rear switch to turn the printer off.
- Use the opening lever to raise the printer cover. If locked, follow the separate cutter guidance below.
- Clear every fragment from the roll holder and exit. If paper will not come free, stop and contact the seller; do not force it.
- Remove feed-path adhesive by the specified cleaning method, then follow Paper Setup.
For cleaning, switch off, unplug and cool the head first; wait until head-cleaning alcohol dries. Ordinary Paper Setup instead starts powered on for automatic feeding. Keep these tasks separate.
If the cover stays locked, first try the normal off/on release. Before opening the front cover, power off and follow the illustrated cutter procedure; keep clear of the blade. Its eight-step sequence ends with power on after refitting and loading. Do not force the cover; ask the seller if recovery is difficult or repeated.
Prevent another jam: paper at the exit or normal waiting?
| Situation | Next check |
|---|---|
| Label waiting | Enabled Hold Print intentionally waits for label removal and is recommended. Check the sensor |
| Paper at exit | Take fully cut output promptly; keep the exit clear. Do not touch moving or uncut paper. Official prevention |
| Roll reloaded | Pull the leading edge straight and use the correct guide and roll orientation. Stock and loading |
Common host comparison: after safe recovery, compare the device-only self-print. If that works but PC/POS output fails, check the queue, connection and same-model driver.
Hold Print · Daily Maintenance
Verified 23 October 2026: SK jam, cutter, loading, maintenance and hold-sensor pages. Earlier software and indicator verification dates remain separate. No physical jam clearing or printing test.
Cool and unplug before cleaning
SK maintenance requires power off/unplug and a cool thermal head. Its head-specific cotton-swab/alcohol method differs from the soft dry cloth for rubber roller and roll-storage path. Wait until head alcohol dries before power on. Avoid scratches/static damage and air blown into the storage path; adhesive/dust need prompt care. For hot-head/board stops, allow the specified automatic cooling instead of repeated driver installation.
Six UEWB SK indicator states and the jam-timing limitation
Select TSP143IV-UEWB SK on the official LED page. Distinguish the left Power/Error (blue/red), middle Bluetooth and right Network indicators. These six selected left-indicator states are not numeric error codes.
| Power/Error light | Meaning and next check |
|---|---|
| Steady blue | Normal Power/Error power state; not proof that a host job printed. |
| Steady red | Cover open. Check paper and close the cover. |
| Red every 0.5s | The paper-out entry. Also read the jam-timing limitation below. |
| Red every 0.125s | The cutter-error entry. Never force the cover or touch the blade. |
| Blue every 0.5s | Hot head pauses output; printing resumes when it cools. |
| Blue every 2s | Hot board pauses output; printing resumes when it cools. |
Jam timing remains unresolved. The official Paper jam error image description and linked animation disagree on timing. Some alternative descriptions also reuse UE indicator labels. Do not distinguish paper-out, jam or cutter trouble solely by flash speed; compare the actual paper condition and corresponding procedure.
- First check whether the roll is empty and the cover is closed. Distinguish a finished label waiting at the exit using the existing Hold Print guidance.
- For an actual jam, power off and follow the removal procedure. For a locked cover, use the cutter-lock guide; never force it.
- If the device self-print works but computer output fails, common host checks are queue, port, model and OS.
