Fix Sunmi V3 Odoo Receipt Printing

@denisSolution

Hi, I'm Denis, a full-stack developer with experience in Odoo POS systems, hardware integration, and Linux troubleshooting. I've resolved similar printer connectivity issues where devices are detected but Odoo doesn't route print jobs to them. Your problem is almost certainly a missing hardware mapping in Odoo's POS module. The Sunmi V3 is recognized by Android, but Odoo doesn't know where to send print commands. This happens when the printer device path isn't registered in Odoo's hardware settings or the ESC/POS driver isn't configured. My approach: First, I'll remotely check Odoo's hardware configuration to verify if the printer is mapped. Then I'll identify the correct device path for your Sunmi thermal printer and configure it in Odoo's POS settings. If needed, I'll install the appropriate ESC/POS driver or set up IoT box integration. We'll test with a sample sale to confirm printing works, then verify it survives reboots and service restarts. The key is ensuring print jobs reach the device at the correct path with the right protocol. Sunmi devices use standard ESC/POS commands, so once hardware mapping is configured, printing should work reliably. I'll document all steps so you can replicate this on your other units independently. One clarification: does your Sunmi V3 have an IoT box, or does Odoo run directly on the device? This determines whether we configure local or network printing—either way, it's solvable. I'm available to start immediately. Thanks, Denis.

Hi, I understand you are facing an issue with your Sunmi V3 terminal where the built-in thermal printer fails to print standard POS receipts when closing a sale in Odoo 19. This seems to be a driver compatibility or configuration problem, as the printer is detected by Android but does not function as expected in the Odoo environment. The primary challenge here is ensuring that the default drivers are correctly interfaced with Odoo's printing system. My approach would involve first verifying the compatibility of the current drivers with Odoo 19 and then checking the configuration settings within Odoo to ensure they align with the printer's requirements. Prioritizing stability and functionality is key to resolving this issue. I have extensive experience with Python and Linux, and have worked on integrating hardware peripherals with software systems in the past, which will be beneficial in troubleshooting and resolving this issue effectively. Q1 – Have you verified if the printer works with other applications outside of Odoo on the Sunmi V3? Q2 – Are there any error logs generated in Odoo or the Android system when attempting to print? Q3 – Have you tried using any alternative drivers or updating the existing ones? Looking forward to hearing from you.

Hi, there, I think you need the Sunmi V3 internal thermal printer working reliably with Odoo 19 POS, without adding unnecessary custom printing layers. I can diagnose where the print flow is stopping, verify the Sunmi printer service and Odoo POS hardware configuration, then configure the correct printer/IoT connection and test a live sale. I’ll also verify printing after both device reboot and Odoo service restart, then provide a short repeatable setup guide for your other Sunmi units. Quick questions: Q1. Is Odoo 19 hosted on your own server/VPS, and can you provide SSH or remote access to the Odoo environment? Q2. When Odoo stays on “Printing…”, does the browser console or Odoo server log show any printer, IoT, or connection error? This will let me trace the actual failure point instead of changing settings blindly. Looking forward to work with you. Thanks Jonas Dedzo

Hi, your issue is clear: Android sees the Sunmi V3 printer, but Odoo POS is not actually using a mapped printing path, so the sale stays stuck on “Printing…”. I’ve worked on POS and device-printing setups where the problem was usually missing printer registration, an incorrect Odoo hardware profile, or relying on the device driver alone instead of the Odoo-supported route. I would first verify how the Sunmi printer is exposed on the device, then check Odoo’s POS hardware settings, printer mapping, and whether an IoT box or the correct Sunmi/ESC-POS path is needed. After that, I’d run a live test sale, confirm the receipt prints automatically, and make sure the setup survives reboot and service restart. I can also leave you a short repeatable setup note for your other units. Best regards, Gabriel

Hi, I can troubleshoot the Odoo 19 POS printing issue and trace the complete path from the POS receipt action to the Sunmi V3 internal printer. I’d first check the Odoo POS configuration, IoT/hardware settings, device registration and the way Odoo is communicating with the Sunmi printer. I’d also inspect the relevant Odoo logs and Android/device-side configuration rather than assuming the default printer driver is the problem. If the standard Sunmi integration is required, I can configure the appropriate connection and adjust the Odoo POS printer settings so the receipt prints automatically after payment. I’ll then test a real sale, reboot the device, restart the Odoo service and repeat the test to make sure the setup survives both. Once working, I’ll provide a short step-by-step guide covering the configuration so you can reproduce it on your other Sunmi terminals. I have experience with Odoo ERP, backend systems, Linux, APIs and technical troubleshooting. I’d start by reviewing the current Odoo version, POS configuration and Sunmi setup remotely. Best regards

Sunmi V3 thermal printers usually break in Odoo POS because it needs the Sunmi print SDK bridged through IoT Box or a direct ESC/POS driver, not the generic browser print path. I can check your Odoo 19 POS config and Android print service logs remotely and get receipts printing again fast. Can start now, realistic fix within 24 hours. Budget and time here are rough given the limited details, happy to confirm exact scope once I see your setup. Send me remote access details and I'll get started.

@lazarr4

Hello, The first thing I’d check is whether the printer is properly registered in Odoo’s hardware settings, since the POS system often ignores unconfigured devices. I’ve helped a client resolve similar issues by ensuring the correct USB/Serial path was set in Odoo’s IoT configuration. I’ve worked with Sunmi V3 devices and Odoo POS before, where the key was mapping the printer via the IoT box or direct USB connection. I’ll verify the printer is detected, then adjust the POS printer profile to use the correct driver. I’d connect via SSH or AnyDesk to: 1. Confirm the printer is listed in Odoo’s hardware settings. 2. Test printing a manual receipt to rule out driver issues. 3. Adjust the POS configuration to trigger the internal printer on sale completion. If the printer isn’t detected, I’ll install the latest Sunmi driver or configure the IoT box to bridge the connection. I’ll document the steps so you can replicate it on other devices. Thanks, Lazar.

Hello, Artur G from Warsaw, Poland here. Your Sunmi V3 Odoo 19 POS setup detects the internal printer but stays on “Printing…” without producing receipts. The key is finding where the print chain breaks between Odoo POS, device configuration, and the thermal printer service. What usually matters here is checking the hardware mapping before changing drivers. I would verify the POS printer configuration, Android printer service, connection path, and Odoo printing flow first, because forcing a driver without locating the issue can create more problems. I have experience with Linux, troubleshooting, automation and device-related integrations. I would trace the receipt request, configure the correct printing path, test a live sale, and document the final setup so it can be repeated on other Sunmi units. Q1 - Is Odoo 19 running directly on the Sunmi device or connecting to a remote server? Q2 - Does the Sunmi printer work from any Android app outside Odoo POS? Q3 - Are other Sunmi V3 units using the same Odoo configuration? Happy to go through the approach in more detail. Looking forward to working with you.

@teksavvy

Dear, Please note that, this requires a module to connect to the Sunmi v3 thermal printer, which is currently missing. So, I have to host the test module or test page to test the printer. Thanks,

Hello, I can troubleshoot the Sunmi V3/Odoo 19 POS printing flow end-to-end, focusing specifically on the device’s built-in thermal printer rather than introducing unnecessary custom drivers. My approach will be to first verify the Sunmi printer service/API, Android permissions, and device configuration, then trace how Odoo POS is attempting to send the receipt. I’ll check the Odoo POS hardware/printer configuration, IoT settings, printer profile, connection method, and relevant Odoo logs to identify why the POS remains stuck on “Printing…”. If required, I’ll configure the appropriate Sunmi integration/driver or Odoo IoT approach, map the internal printer correctly, and validate the receipt flow with a live test sale. I’ll also verify persistence after both a device reboot and an Odoo service restart. I’m comfortable working with Odoo POS, Android POS terminals, Sunmi hardware, ESC/POS printing workflows, USB/serial/network printer configuration, and IoT integrations. I’ll avoid changing working components unnecessarily and will document exactly what was configured. ==> Deliverables: Root-cause diagnosis Correct printer/IoT configuration Working automatic receipt printing Verification after reboot/service restart Short step-by-step setup guide for your other Sunmi V3 units I can work remotely through AnyDesk, SSH, or another mutually agreed secure method. Once access is available, I can start immediately - Abhi

Hi, I’ll get your Sunmi V3 internal printer printing Odoo 19 POS receipts end-to-end, including diagnosing why the receipt is stuck on “Printing…”, configuring the correct Sunmi/Odoo printer path, and validating auto-print after reboot. The main technical concern is that the built-in printer may be detected by Android but not actually mapped into Odoo’s POS hardware flow, so I’ll verify the device registration, driver/IoT path, and POS printer profile. I recently worked on POS receipt-printing issues involving Android handhelds and ESC/POS-style mapping. For your project, I’d begin by checking Odoo’s POS hardware settings and Sunmi printer registration, then complete a live test sale and confirm persistence after restart. Have you already enabled the Sunmi printer service or connected this device to an Odoo IoT box? Best regards, NexLoom

@sara0346

Hello, I reviewed your Sunmi V3 Odoo 19 POS printing issue. I will diagnose why Odoo remains on “Printing…” and verify the communication between the POS and Sunmi’s built in thermal printer. I will configure the correct printer or IoT connection and adjust the required Odoo settings. I will complete live receipt testing and verify printing after reboot and Odoo restart, then provide clear setup notes for your other devices. I am ready to start immediately. One key question: do you already have remote access available to the Sunmi device and Odoo server? Best Regards, Sara

Hi, starting with a remote session to check your Sunmi V3's built-in printer service and how Odoo POS is trying to reach it. Getting your receipts to print automatically on the device's internal printer is the goal. Previously I configured Odoo POS with Sunmi terminals where the fix was installing the Sunmi JS SDK on the device and enabling the direct print module, since Odoo cannot see the built-in printer without it. I would diagnose why the print job never leaves Odoo, install the correct driver or IoT configuration, adjust your POS printer settings, and test a sale end to end. You will get a short step-by-step note so you can repeat this on your other Sunmi units. Confident I can resolve this quickly if awarded. Talk soon.

⭐ Similar Experience: Untangling “Printing…” dead-ends on Sunmi terminals running Odoo POS, from driver mapping to IoT box quirks. Hi there, ✋ I've finished the reading your job description and I really get who you're looking for. I'm writing this proposal by hand, as a developer who has pretty rich experience in hardware-integrated Odoo POS setups that love to silently swallow receipts. Your Sunmi V3 bug is a classic: Android sees the thermal printer, but Odoo POS has no idea how to route the job, so it just smiles and says “Printing…” forever. I'll trace that ghost, map the printer through the right Odoo IoT profile, and get a real receipt in your hand. On the Python side, Odoo's POS print stack and IoT long-polling routes are where I'll dig first , I'll adjust the printer profile, USB/Serial path and IoT box config so the internal head fires automatically once a sale closes. The architecture matters here: I'll structure the device-to-server path so it survives reboots and Odoo service restarts, not just the first lucky test. And since your team will stare at this daily, I'll keep the setup clean and predictable , no fragile interface hacks that break on the next device. You'll get a live test sale printing start-to-finish, plus a short step-by-step note so you can replicate it on your other Sunmi units. Likely a quick win , let's make that printer finally earn its keep. ⏱️ => ⏱️ I'm available for 40+ work hours per week for this projects, and I'm totally flexible
