POS Printer Not Printing Receipts? How to Fix Error 8701 & Blank Pages
Quick Summary: A POS printer not printing receipts is usually caused by one of four things: a power or cable disconnection, thermal paper loaded the wrong way, a network IP address change (often triggering Error 8701), or a corrupted printer driver. This guide walks through a 60-second diagnostic checklist, then provides step-by-step fixes for blank receipts, network communication failures, paper jams, and driver issues — most resolved without a service technician.
The fastest way to fix a POS printer that is not printing: check that the power indicator light is solid green or blue (not flashing red), confirm the thermal paper is loaded with the coated side facing the printhead, and reseat all USB or Ethernet cables at both ends. If the printer produces a successful self-test page but does not respond from the POS terminal, the fault is in the connection, IP address configuration, or printer driver — not the printer hardware itself.
Why Is My POS Printer Not Printing Receipts?
Before opening any settings panel or reinstalling drivers, start with a 60-second hardware check. The majority of POS printer not printing cases trace back to a physical issue that a quick inspection can identify.
60-Second Diagnostic Checklist:
Step 1 — Check the Power Status. The printer should display a solid blue or green indicator light. A flashing red light typically signals an empty paper roll, an open cover, or an overheated printhead. No light at all means the power cable is disconnected or the outlet is dead.
Step 2 — Run a Self-Test. Turn the printer off. Hold down the FEED button, then turn the printer back on while holding the button for 3 seconds. If the printer produces a clean status page, the hardware is functioning correctly — the problem lies in the cable connection, the POS software configuration, or the network setup.

A quick walkthrough covering cable checks, thermal paper placement, and driver verification:
How Do I Fix a POS Printer That Prints Blank Receipts?
If the printer mechanism is making noise and feeding paper normally but no text appears on the receipt, it is almost certainly a thermal paper issue. Modern POS receipt printers use heat-sensitive paper — not ink ribbons or cartridges — so the paper orientation matters.
1. Perform the Scratch Test. Scratch both sides of the receipt paper with a fingernail. The side that leaves a dark black mark is the thermal coating. This coated side must face the thermal printhead directly. If the wrong side is facing the printhead, the paper passes through the mechanism untouched.
2. Correct the Roll Placement. Open the top cover, remove the paper roll, and flip it so the paper feeds from the bottom up (or according to the loading diagram printed inside the cover). Loading the roll upside down is the single most common cause of blank receipts across all thermal printer models.
3. Verify the Paper Type. Confirm that the loaded paper is actually thermal paper, not standard bond paper. Bond paper will not react to the printhead's heat regardless of which side faces up. A quick way to verify: hold a lighter flame near the edge of the paper — thermal paper darkens immediately; bond paper does not.
What Should I Do If My POS Machine Stops Printing?
If the printer is completely unresponsive — or if the POS screen displays Error 8701 (a common fault code indicating a network timeout or communication failure) — it is almost certainly a connection issue. When the POS software cannot locate the printer's IP address or detect the USB device, it triggers this offline error. The following steps address the most common causes:
Fix Dynamic IP Address Changes (LAN/Wi-Fi Printers). When a store's router restarts, it may assign a new IP address to the network printer, which breaks the connection configured in the POS software. To resolve this: print a self-test page to find the printer's current IP address, update the address in the POS software settings, and then configure the router's DHCP reservation to assign a static IP to the printer's MAC address. This prevents the address from changing after future router restarts.
Check Physical Cable Connections. Unplug and firmly reconnect the USB, Ethernet, or serial cable at both the printer end and the terminal end. Check that no port is loose and that the cable itself is not damaged. A partially seated Ethernet connector is a frequent cause of intermittent printing failures that appear random.
Rule Out a Cash Drawer Short Circuit. A short circuit in the cash drawer's kicker solenoid can freeze the printer's controller board, because most cash drawers receive their open signal through a cable connected to the printer. Unplug the RJ11 cable connecting the cash drawer to the printer, restart the printer, and attempt to print. If printing resumes, the cash drawer cable or solenoid is the fault point. For further diagnosis, see: Common POS Cash Drawer Problems and Fixes.
Is It a Paper Jam or a Driver Issue When a POS Printer Won't Print?
Identifying whether the fault is mechanical or software-related determines the correct fix. Here is how to tell the difference:
If the printer beeps, flashes a red error light, makes grinding noises, or the auto-cutter blade is visibly stuck halfway through a cut — it is a mechanical issue (paper jam or cutter failure). If the printer feeds paper smoothly but prints rows of random characters, question marks, or garbled text — it is a driver or configuration issue.
Fixing Driver Issues (Garbled or Random Characters). A recent operating system update can corrupt the installed printer driver or change the default communication settings. Uninstall the current printer driver from the terminal's device manager, restart the terminal, and reinstall the latest driver version from the printer manufacturer's website. For printers connected via a serial (COM) port, verify that the baud rate setting in the driver matches the baud rate configured on the printer itself — a mismatch produces gibberish output.
Clearing a Paper Jam and Auto-Cutter Error. Turn off the printer immediately to prevent damage to the cutter motor. Open the front cutter cover (most models use a slide-up mechanism) and manually rotate the internal gear until the cutter blade retracts fully. Remove any crumpled or torn paper fragments from the paper path before reloading a fresh roll.
Cleaning the Printhead. Accumulated dust, adhesive residue from label stock, or paper coating buildup on the thermal printhead can cause faded prints, partial lines, or false sensor readings. Turn off the printer and wait for the printhead to cool. Wipe the printhead surface gently with a lint-free cloth moistened with isopropyl alcohol. Allow the alcohol to evaporate completely before powering the printer back on.
Frequently Asked Questions
Why is my POS printer not printing receipts?
This is typically caused by a power disconnection, an open printer cover, a network IP address change, or a corrupted printer driver. Running a self-test — hold the FEED button while powering on — isolates whether the issue is hardware or software related. A successful self-test print means the printer hardware is working and the fault lies in the cable, network, or POS software configuration.
How do I fix a POS printer that prints blank receipts?
Blank receipts are almost always caused by the thermal paper being loaded with the wrong side facing the printhead. Open the cover, scratch both sides of the paper with a fingernail — the side that leaves a dark mark is the thermal coating — and reload the roll so that coated side faces the printhead. Also verify that the paper is thermal paper, not standard bond paper.
What should I do if my POS machine stops printing?
Check all physical connections (USB, Ethernet, or serial cables) and confirm the power indicator light is solid, not flashing. For network-connected printers, print a configuration page to check whether the IP address has changed — a router restart can reassign the IP and break the connection. Restart both the POS software and the printer after reseating the cables.
Is it a paper jam or a driver issue when a POS printer won't print?
If the printer flashes a red error light, makes grinding noises, or the auto-cutter blade is stuck halfway, it is a physical paper jam. If the printer feeds paper smoothly but prints random characters or gibberish, it is a driver corruption or baud rate mismatch — uninstall the current driver, restart the terminal, and reinstall the correct version from the printer manufacturer.
Conclusion
Most POS printer failures fall into one of four categories: power and cable faults, thermal paper orientation, network IP changes, and driver corruption. A 60-second self-test isolates whether the fault is inside the printer or in the external connection — and from there, each fix follows a clear sequence that does not require specialized tools or a service technician.
If the printer requires constant resets, produces inconsistent print quality after cleaning, or has a failing auto-cutter that jams repeatedly, the printhead or controller board may be reaching end of life. For high-volume retail and food-service environments, TCANG's 80mm thermal receipt printer line uses heavy-duty auto-cutters rated for extended daily operation and supports ESC/POS command compatibility across major POS platforms.
