Star Micronics TSP100 cuts receipt mid-line — auto-cutter misalignment, end-of-page detect & cutter timing profile
Technician
• Which exact model shows on the sticker: TSP100, TSP100III, or TSP143?
• How is it connected — **USB**, LAN/Ethernet, or serial?
• What are you printing from: Windows POS app, browser-based POS, or macOS CUPS queue?
• Symptoms: does the receipt stop exactly in the middle of a line, cut off totals/footers, or perform multiple cuts on long receipts?
Technician
• A **paper size / receipt length** (e.g., 72mm x receipt, custom length).
• A **cut command** (full cut / partial cut) at the end of what the software thinks is the page.
• Optional **futurePRNT “End Page Detect”** settings that decide whether the cut happens after a Form Feed or at the tear-bar.
If the Windows driver, POS template, and **cutter timing profile** don’t agree, the TSP100 will cut too early — often mid-line. We’ll adjust: 1) Windows printing preferences, 2) futurePRNT cutter options, and 3) POS layout/margins so the receipt ends after the last line, not through it.
Technician
On your POS PC:
1) Open Control Panel → Devices and Printers, right-click Star TSP100 → Printing preferences.
2) Under Paper / Layout / Advanced, set the **paper size** to a proper receipt size (e.g., 72mm x Receipt or 80mm x 2000mm depending on the driver). Avoid tiny custom heights — that makes the driver think the page ends early and sends a cut.
3) In the driver’s **Printer Features / Cut Options**, set **Document Cut Type = Partial Cut** and **Page Cut Type = Partial Cut** (or “Cut at end of document only” if that’s the wording). This tells the TSP100 to only cut after the full receipt, not mid-page.
4) Click Apply, then print the driver’s own **test receipt** (not from POS) to confirm the new cutter timing profile behaves properly on long output.
Technician
The TSP100 uses **futurePRNT** to decide when the receipt is “done”. If it’s tuned wrong, the cutter timing doesn’t line up with your POS layout.
• Open the TSP100 futurePRNT Configuration utility on the Windows machine.
• Look for the End Page Detect settings: options like “Cut or Feed to Tear Bar Commands” vs “Form Feed Command”.
• For most POS apps, you want the printer to treat the **cut command** as the end of the receipt, not a random form feed in the middle. Select the mode recommended for **receipt printers** (not report printing).
• Save the settings to the printer, then print the built-in **futurePRNT sample receipt** to verify the cutter makes a clean partial cut after the footer/logo.
If your POS has a template editor, make sure there’s at least one blank line or line feed after the totals so the bottom of the receipt isn’t riding the exact cut position.
Technician
If you’re printing from a browser-based POS or PDF template:
• In the browser’s Print dialog, set **Scale = 100%** or a slightly lower value (e.g., 90–95%) instead of “Shrink to fit” if your vendor recommends a specific percentage for Star TSP100.
• Disable extra **headers & footers** (page title, URL, date) — they eat vertical space and can push your totals into the cutting zone.
• Make sure the page size in the browser matches the **custom receipt size** you set in the TSP100 driver; otherwise Windows assumes a different “bottom of page” and sends a late cut command mid-text.
• For very long receipts, check your POS vendor docs for a “long receipt mode” or recommended **cutter profile** for Star printers so the job doesn’t break into multiple pages.
Technician
A slightly locked or mis-homed cutter can make the printer stop early:
1) Power the printer **off**, wait 10–15 seconds, then hold the feed button while turning it **on** to print the **self-test**. Confirm the cutter does one clean partial cut at the test page end.
2) If it stalls, follow the Star “reset auto-cutter” procedure: open the cover, gently move the cutter to its home position as described in the manual, clear scraps of paper, then close and power on again.
3) Reload the paper so it sits firmly against the **back stop**, not angled, and confirm the roll width matches the driver’s paper width (e.g., 80mm vs 58mm).
4) Re-run a long test from the POS — if the hardware cut is now smooth and the driver’s timing is correct, the receipt should no longer be cut mid-line.
Technician
• On each POS PC, save a **TSP100 printing preset** with the correct paper size, Document Cut Type/Page Cut Type = Partial Cut, and “cut at end of document only” behavior, then set it as the default.
• In futurePRNT, export the **configuration profile** and import it on other stations so all Star TSP100 printers use the same cutter timing and end-of-page detect settings.
• Ask your POS vendor whether they have a “Star TSP100 cutter profile” or recommended template; many cloud POS systems ship a default designed for Star’s 72mm x 2000mm receipts.
• Any time Windows or POS updates, quickly run one **long test receipt**; if you see the cut drift again, you’ll know to re-apply the saved profile before live customers notice.
Technician
• They all use the same basic **thermal mechanism and auto-cutter** logic.
• On Windows/macOS, you’ll always see **paper size**, **cut options**, and an **end-of-page/cut mode** in the Star driver or CUPS web interface.
• futurePRNT still controls how the printer treats **cut commands vs form feeds**.
So the same steps — correct paper size, proper **cutter timing profile**, and a quick cutter reset — stop the “Star TSP100 receipt cuts mid-line” problem on the whole family.

Quick answer: the accepted fix
Accepted fix when a Star Micronics TSP100 cuts receipts mid-line: set a correct receipt paper size in the driver, change Document/Page Cut Type so the printer only performs a partial cut at the end of the receipt, and tune the futurePRNT end-of-page detect so the cutter triggers after the final line, not on a random form feed. Reset the auto-cutter and test with a long POS receipt to confirm clean cuts after the footer.
Why Star TSP100 receipts get cut in the middle of a line
With the TSP100 thermal receipt printer, the auto-cutter doesn’t “guess” where to cut — it listens to the **driver and POS software**. If the driver thinks the page height is shorter than your real receipt, or the POS sends a cut / form-feed command too early, the result is a receipt cut off in the middle of text. Misconfigured futurePRNT End Page Detect options can also cause the printer to treat an internal control code as the end of the page and fire the cutter prematurely.
How to check the Star TSP100 cutter timing profile
To verify that the cutter timing profile is correct, run three quick tests: (1) a Windows or CUPS test page using the Star driver, (2) a futurePRNT sample receipt, and (3) a real POS receipt with many items. In each case, the TSP100 should print to the end, add a small blank gap, and then perform a single partial cut across the feed channel, not through any printed line. If any one of those tests is cut short, adjust the **paper size**, **cut options**, and **end-of-page mode** again until all three outputs cut cleanly after the footer.
TSP100 cutting receipts short — quick troubleshooting tips
Most “receipt cut off” cases are driver paper size, cut options, or POS layout — not a bad printer.
Quick path: open the Star TSP100 driver → set a proper receipt paper size → configure Document/Page Cut Type for partial cut at end of document → adjust futurePRNT End Page Detect → reset the auto-cutter and run a long test sale. This combination resolves the majority of Star Micronics TSP100 cuts mid-line issues across Windows, macOS CUPS, and browser-based POS systems.

FAQ
Why does my Star TSP100 cut receipts in the middle of a line?
Usually because the **paper size**, **cut options**, or POS template are misconfigured. The driver thinks the page ends sooner than it really does, sends a cut command early, and the auto-cutter slices through the last printed line instead of after the footer.
How do I change the cutter timing profile on a TSP100?
Use the Star TSP100 driver (Windows/macOS) to set the correct receipt paper size and adjust **Document/Page Cut Type** to cut at the end of the receipt. Then use the futurePRNT utility to configure how the printer detects the end of the page (cut vs form feed) and save that profile to the printer.
Can a jammed cutter make the TSP100 cut receipts short?
Yes. If the auto-cutter is partially locked or not homed correctly, it can stop the paper path early. Power-cycle the printer, run the Star auto-cutter reset procedure, clear scraps of paper, and re-test with a long receipt after adjusting the driver settings.
What if receipts still cut off after fixing driver and futurePRNT settings?
Check your POS vendor’s Star TSP100 setup guide, verify browser/PDF scale and headers, and make sure only one TSP100 driver/queue is active. If the issue persists, a specialist can review screenshots of your driver, CUPS, and POS template to pinpoint the remaining mismatch.
