# SM-T300 Printer Configuration

<p class="callout info">The SM-T300 Printer is a mobile Bluetooth hardware printer used to issue physical citations from the OPS-COM Enforce application. Its primary purpose is to print physical tickets in the field, and this guide outlines how to configure its core hardware connection and power-saving settings. This article is intended for OPS-COM administrators and field enforcement personnel.</p>

## Setup and Configuration

Before the SM-T300 printer can successfully pair with your Android handheld and print tickets, you must ensure its internal hardware settings are configured to broadcast a standard Bluetooth signal and manage power efficiently. All setup is performed directly on the physical printer using it<span class="citation-2901 citation-2902 citation-end-2902">s hardware buttons.<sup class="superscript embedded" data-turn-source-index="1"></sup></span><span class="citation-2901 citation-end-2901"><sup class="superscript embedded" data-turn-source-index="2"></sup></span>

<span class="citation-2891 citation-end-2891">Enforcement personnel must interact with the physical buttons on the printer's front panel to navigate its internal menus and adjust the operational modes.<sup class="superscript embedded" data-turn-source-index="12"></sup></span>

### <span class="citation-2890 citation-end-2890">Configuring Bluetooth Mode<sup class="superscript embedded" data-turn-source-index="13"></sup></span>

<span class="citation-2889 citation-end-2889">To pair <sup class="superscript embedded" data-turn-source-index="14"></sup></span>the printer with a handheld device, the printer must be set to the standard Bluetooth mode, rather than UART or Bluetooth (iAP).

1. Hold down the **Feed** button and **Power** button simultaneously for approximately 6 seconds until the printer enters setup mode.
2. Press the **Power** button to cycle through the available connection modes.
3. Stop cycling when the screen displays **Bluetooth.**
4. Hold down the **Feed** button and **Power** button simultaneously for approximately 6 seconds to confirm and save your connection setting.

### Configuring Power Down Settings

To preserve battery life during patrols, you can configure the printer's timeout setting. It can be set to "no power down" or configured to power down automatically after 1 to 5 minutes of inactivity.

1. Turn the physical printer on.
2. Press and hold the **Power** button, then immediately press and hold the **Feed** button at the same time for approximately 5 seconds until the screen becomes backlit and enters Settings mode.
3. Press the **Feed** button to step through the settings menu until the screen displays *PWDN X min off* (where X represents the current timeout duration).
4. Press the **Power** button to cycle through the available timeout options.
5. Press the **Power** button and **Feed** button simultaneously once you have selected your desired wait time.

<p class="callout info">**Configuration Confirmation** Once you save your power down settings by pressing both buttons simultaneously, the SM-T300 will automatically print out a short paper summary of your current settings and return to standard standby mode.</p>

## <span style="color: rgb(22, 145, 121);">Best Practices and Considerations</span>

- <span style="color: rgb(22, 145, 121);">**Optimize your battery life:** **Always configure a power down timeout of 3 to 5 minutes to ensure the printer battery lasts through an entire enforcement shift.** Leaving the printer constantly powered on when not actively ticketing will drain the battery prematurely.</span>
- <span style="color: rgb(22, 145, 121);">**Verify connection modes:** **If your Android tablet cannot discover the printer during the initial pairing process, verify that the printer is in standard Bluetooth mode.** If it is accidentally set to Bluetooth (iAP), which is generally reserved for iOS devices, standard Android tablets will struggle to connect.</span>
