Troubleshoot your Toast Printing Hub.
Troubleshoot your Toast Printing Hub (TP300) when it won't power on, isn't printing, prints duplicates, or its accessories aren't working. Use this article before contacting Toast Customer Care.
Important: The Toast Printing Hub (TP300) is designed for the Toast Flex 3 terminal. If you connect a TP300 to a Toast Flex 14 terminal and your terminal won't power on, the USB Power Plus Cable is not able to power a Flex 14 terminal; your Flex 14 needs its own power supply. You can upgrade to a Flex 3 terminal, or you can purchase a Printing Hub Adapter on the Toast Shop. See Toast Flex 3 Hardware Compatibility before continuing.
Applies to: Toast Printing Hub (TP300), Toast POS, Toast Flex 3 terminal, Toast Flex 14 terminal | Permissions needed: 4.5, 6.2, 6.6, 7.1, 7.2, and 7.3 permissions.
What you'll accomplish: Identify the symptom on your Toast Printing Hub (TP300), follow the matching troubleshooting branch, and resolve most issues without contacting Toast Customer Care.
Required: physical access to the Toast Printing Hub (TP300), the connected Toast terminal, and Toast Web access for menu routing issues.
For most Toast Printing Hub (TP300) issues, work through these high-level steps first:
If none of those fix the issue, use the Quick Fix table below or jump to the matching troubleshooting branch.
Match your symptom to the row below and try the quick fix first. If it doesn't resolve the issue, jump to the matching detailed section.
| Symptom | Most common cause | Quick fix | Self-service? |
| Printer has no power (Power LED off) | Power adapter not seated, bad outlet, or damaged adapter | Reseat the power adapter, try a different outlet, or test with a known working adapter | Yes |
| Terminal won't power on after connecting a new TP300 | Terminal is a Flex 14 (not supported for USB power via TP300), or USB Power Plus Cable is not seated | Reseat the USB Power Plus Cable on both ends; confirm terminal model. If Flex 14, the terminal needs its own power supply or a Printing Hub Adapter needs to be purchased. | Yes |
| Printer is offline / not printing (Network LED solid orange) | Local network up but internet or ISP down, or Ethernet cable in the wrong port | Confirm Ethernet cable is in Ethernet In (not Ethernet Out), reseat the cable, and check your router | Yes |
| Printer is offline / not printing (Network LED flashing orange) | Printer can't reach the router | Trace cables to the router, check any network switches, reseat cables | Yes |
| Prints duplicates or prints to the wrong station | Menu routing or prep station configuration in Toast Web, or "Always Print" / "Send to Expo" enabled unintentionally | In Toast Web, check Menu Manager, Prep Station, and Advanced Properties for the affected items | Yes |
| Cash drawer won't open | Drawer not enabled under Printer Setup, RJ11 cable loose, or no receipt printer selected | Confirm cash drawer is selected for the Printing Hub in Printer Setup; confirm a receipt printer is selected in Device Setup > Receipt Printer; reseat the RJ11 cable | Yes |
| Accessory not detected (card reader, scanner, scale) | USB cable not seated, or Terminal LED orange/off | Reseat the USB cable; check the Terminal LED; power cycle the printer | Yes |
| Printer Error LED flashing red | Hardware error (paper jam, paper installed backward, internal fault) | Check for paper jams, confirm paper roll glossy side faces the status LEDs, power cycle the printer | Partial—true hardware faults require Customer Care |
Watch this short video for a visual overview of Toast Printing Hub (TP300) troubleshooting.
If your Toast Printing Hub (TP300) appears completely dead, start by checking the Power LED on the front of the printer.
What to do next:
Expected outcome: The Power LED turns green and the printer is on.
If the Power LED is still off after these steps, the printer may have a hardware fault. See Before You Contact Customer Care.
If you installed a new Toast Printing Hub (TP300) and your Toast terminal won't power on, the cause is usually one of the following.
Identify your terminal first. The USB Power Plus Cable that ships with the Printing Hub (TP300) only delivers power to a Toast Flex 3 terminal. It does not power a Toast Flex 14 (Old Gen) terminal. See Toast Flex 3 Hardware Compatibility for the full compatibility matrix.
Expected outcome: The terminal powers on and the Printing Hub's Terminal LED turns green.
If your Toast Printing Hub (TP300) isn't showing any errors but still isn't printing or appears offline, the POS may be having trouble communicating with the printer. The Printing Hub can be connected by network (Ethernet) or by USB.
Common symptoms: Printer offline, printer won't print, Network LED orange or flashing, can't add printer to the POS.
If your Toast Printing Hub (TP300) is connected to the network and isn't printing or shows as offline, check the Network LED on the front of the printer.
Expected outcome: The Network LED turns solid green and the printer appears as Connected in Printer Setup.
If your Toast Printing Hub (TP300) is connected only through USB and isn't printing or shows as offline, check the Terminal LED on the front of the printer. With USB-only connection and no network, the printer only receives print jobs from the connected terminal.
What to do next:
Expected outcome: The Terminal LED turns green and the printer can receive print jobs from the connected POS device.
If the Printing Hub's network or USB connection looks good but the printer still won't print, check the printer status on your Toast POS device.
Expected outcome: The printer shows as Connected in Printer Setup and successfully prints a test ticket.
If the printer still appears offline after these steps, see Before You Contact Customer Care.
If your Toast Printing Hub (TP300) is online but won't print, prints duplicates, or prints tickets to the wrong place, the cause is usually a configuration issue rather than a hardware issue.
If your device is not printing receipts:
If your device is printing duplicates:
Expected outcome: Items print once, at the correct station, with the receipt configuration you intended.
Common symptoms: Printer jammed, printer not printing, Error LED flashing red.
The Toast Printing Hub (TP300) has an Error LED on the front panel. If you suspect a hardware issue, the Error LED should be flashing red. For more detail, press the orange power button twice in rapid succession to print an Advanced Diagnostic Report.
If there's a hardware issue, try the following:
Expected outcome: The Error LED is no longer flashing red and the printer prints test tickets successfully.
If none of these resolve the issue, see Before You Contact Customer Care.
The Toast Printing Hub (TP300) supports several accessories, including scanners, weighing scales, cash drawers, and card readers.
Common symptoms: Scanner not scanning, scale not weighing, card reader not connecting, cash drawer not opening.
If a USB accessory plugged into the Printing Hub isn't working as expected:
Expected outcome: The accessory's status reflects an active connection on the Toast POS, and the device functions as expected (scan, weigh, or process payment).
For more on identifying and setting up card readers, see "Checking Your Card Reader Type."
If your cash drawer is connected to the Toast Printing Hub (TP300) and won't open:
Expected outcome: The cash drawer opens when a payment is completed at the connected POS.
If the cash drawer still won't open, see Before You Contact Customer Care.
When asked to share a diagnostic slip with Toast Customer Care, the Toast Printing Hub (TP300) can print three types of reports. Use the Diagnostic Report or Advanced Diagnostic Report for detailed troubleshooting information.
The Startup Status Slip prints automatically when the printer powers on. It provides at-a-glance information about the device and its status, including:
To print one, turn the printer off, then back on. The slip prints automatically after about 10 seconds.
Expected outcome: A printed slip with the device's current status. Keep this slip—Customer Care may ask for the Serial Number or IP address on it.
The Diagnostic Report contains key information about the printer's status, including connection details, errors, and troubleshooting hints.
To print one, press the orange power button twice in rapid succession while the printer is on. The report prints automatically.
Expected outcome: A printed Diagnostic Report.
The Advanced Diagnostic Report contains more detailed information than the standard Diagnostic Report.
To print one:
Expected outcome: A printed Advanced Diagnostic Report.
