Frequently asked questions about the TP300 Printing Hub Adapter for Flex 14, covering setup, features, compatibility, and troubleshooting.
The Printing Hub Adapter is a cable accessory designed to enhance compatibility between the Toast Receipt Printing Hub (TP300) and the Flex 14 (TT200) terminal. It enables features such as power delivery, Ethernet over USB-C, direct USB printing, and peripheral USB hub access — all through a single cable connection.
The Printing Hub Adapter is specifically engineered to connect Flex 14 (TT200) to the Toast Receipt Printing Hub (TP300):
Note: It is not compatible with other Toast terminal models.
Without the Printing Hub Adapter, the Flex 14 terminal is not compatible with the TP300 — it can only connect over the network and cannot use USB-C features, power delivery, or accessories plugged into the TP300's USB hub. The adapter is required to unlock the full feature set of the TP300 when paired with a Flex 14.
When properly installed, the Printing Hub Adapter enables the following through a single cable connection:
Follow these three steps to connect the adapter:
For full installation instructions, see the Printing Hub Adapter User Guide.
The adapter includes integrated thumbscrews on the "To TP300" connector. After plugging the adapter into the USB-C port on the TP300, tighten these thumbscrews by hand to lock the connection in place and prevent accidental disconnects.
The adapter package includes the Printing Hub Adapter cable itself. The Toast USB-C cable used to connect the adapter to the Flex 14 terminal is provided with the TP300 Printing Hub. An RJ45 Ethernet cable is also included to connect the printer to a local outlet or switch, and a wall mounting kit is included with mounting screws.
Yes. After completing the hardware setup, navigate to Printer Setup on your Toast POS and follow the prompts to add or replace the printer. This POS setup step is required to route print jobs to the TP300 regardless of your connection method. See the Toast Printing Hub Installation Guide for details.
The TP300 acts as the power source for the Flex 14 terminal when the adapter is connected. Power is delivered from the TP300 through the adapter and USB-C cable to the terminal, so the Flex 14 does not need a separate power supply when this setup is used.
The adapter supports Ethernet over USB-C technology. When the TP300 is connected to your POS network via Ethernet, the Flex 14 terminal can share that network connection through the adapter — without requiring a separate Ethernet cable run to the terminal.
The adapter enables Direct-Print over USB-C as a backup connection. If your network becomes unavailable, the Flex 14 can continue to send print jobs directly to the TP300 over the USB connection, ensuring printing is not interrupted during network outages.
Yes. When the adapter is connected, any peripherals plugged into the TP300's USB-A or USB-C ports (such as barcode scanners, scales, or card readers) become accessible to the Flex 14 terminal. This means you do not need separate USB connections from each peripheral directly to the terminal.
Yes. Connect your cash drawer to the dedicated cash drawer port on the TP300 (bottom right of the printer hub). For setup instructions, refer to the Setting Up Cash Drawers article on the Toast Support site.
No. The Printing Hub Adapter is designed exclusively for the Toast Flex 14 (TT200) terminal. The Flex 3 terminal uses the Power Plus Cable included with the TP300 and does not require the adapter.
No. The adapter is only compatible with the Flex 14 (TT200).
For full functionality, yes. Connecting the TP300 to your POS network via Ethernet is recommended so that all POS devices on the network can print to it. However, if your use case requires only the connected Flex 14 to print, the Direct-Print over USB-C feature (enabled by the adapter) allows printing without a network connection.
No. The Flex 3 Guest Display can only be connected to the Guest/Peripheral port in the base of the Counter Terminal or on the back of the terminal — it cannot be connected through the TP300.
Try the following steps:
If the issue persists, contact Toast Support.
An orange Terminal LED indicates the printer detects a connection but is not receiving active data from the terminal — typically because the Flex 14 is not powered on or has not finished booting. The TP300 will continue to function normally. Power on the Flex 14 and allow it to boot fully; the Terminal LED should turn green once communication is established.
Try the following:
For comprehensive troubleshooting steps, refer to the Get Help With the Toast Printing Hub article on the Toast Support site. You can also print a Diagnostic Report from the TP300 by pressing the power button twice in rapid succession while the printer is on.
