How can I download my text messages without a sims card so I can print on my computer to save?
You can use this app to create an xml file of your text messages. Then you can email over Wifito yyourself or connect the phone to the computer via USB cable and copy the file from the SMS Backup folder. The xml file can be opened with Internet Explorer or Excel and printed out.
