The SM-T300 is a mobile Bluetooth hardware printer used to issue physical citations from the legacy OPS-COM Android enforcement 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.
## 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 its hardware buttons. ### Configure Bluetooth Mode To pair the printer with an Android 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. ### Configure 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.**Configuration Confirmation** Once you save your power down settings by pressing both buttons, the SM-T300 will automatically print out a short paper summary of your current settings and return to standard standby mode.
--- ## Best Practices and Considerations - **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. - **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. --- ### Supporting References For more advanced configuration or troubleshooting, administrators can refer to the official Star Micronics resources and SDK documentation below: - [https://play.google.com/store/apps/details?id=com.StarMicronics.StarIOSDK](https://play.google.com/store/apps/details?id=com.StarMicronics.StarIOSDK)
