How to Print Text Messages Off of Your Galaxy S III

Software Option
1. Download BackupTrans Software’s “Android SMS + MMS Transfer” software (see Resources). This software extracts SMS and MMS messages from any Android device and stores them for backup on your PC. With the free software, you can view and transfer a limited number of text messages; with the licensed version ($29 as of August 2013), you can transfer unlimited texts on up to three devices.
2. Connect your Galaxy S3 to your computer using the provided miniUSB cable, wait for your computer to recognize the device and then launch Android SMS + MMS Transfer. The software will scan your drive and create a list of items that it can sync to your computer; the first time you connect the Galaxy, this process may take a few minutes.
3. Click on “Galaxy S3” under the list of devices in the left-hand panel of the software. Select the messages you want to print from the list, click “File” and choose “Print SMS and MMS.” Select your printer and confirm the print settings (using the visual print preview) and then click “Print.”
App Option
4. Press the “Home” button on the Galaxy S3 and swipe your phone to unlock it. Tap the “Google Play” icon to open the application market. You need to be connected to the Internet to download apps, so make sure your phone has either a 4G or Wi-Fi connection. Search for “PrinterShare Mobile Print.” Tap “Install” to download and install the software.
5. Connect your phone to Wi-Fi, if it isn't already, and ensure that your printer is turned on. Both the printer and the phone need to be on the same wireless network in order for PrinterShare Mobile Print to work properly. Tap the app to open it and wait while it searches the network for the printer.
6. Tap “Messages” to open your SMS and MMS messages in PrinterShare. Select a conversation that you wish to print and then choose your printer from the list or tap “Nearby – WiFi” to select the closest wireless printer available. Additionally, you can print to a Bluetooth or USB printer using the Samsung miniUSB to connect to the printer. With the free version of the software, you can print up to 20 pages. After that, you need to buy PrinterShare Premium Key for $13 through Google Play.
Manual Method
7. Tap 'Messages' on your phone to view the text messages and then click on a conversation with messages you want to print. Tap and hold on any of the speech bubbles and then tap 'Copy message text.'
8. Press the 'Home' button to return to your Home screen and then tap 'Email' to open the email app. Compose a new message to yourself and then tap and hold in the body of the message and press 'Paste.' Repeat these two steps until all of the messages you want to print are in the email body. Tap 'Send.'
9. Open the email on any computer connected to a printer and then click 'File,' and choose 'Print' in your Web browser. The formatting of the text messages may not be perfect from the copying-and-pasting, so you may wish to copy these texts into a word processor before printing.
