"print" is for creating the kinds of outputs that might be sent to a printer. Is that what you want? Or are you looking to create a text file?

Ya i want to use the print command or print function.
I have to take the data from the text box and get it printed solely.
So what is the coding used for this?

Let h be the handle of the uicontrol of style Text. Then
h_handle = handle(h);
h_image = h_handle.getPrintImage;
At this point, h_image will be an RGB array containing a rendered copy of the text. You can now figure() a new figure, image() h_image into the new figure, and print() the new figure.
You might wish to consider, however, using imwrite() on h_image to save it to an image file that you can print using your system utilities.
I have my doubts that any of this is what you really want to do, but...
