3M Printscape

3M Printscape software was included for free with many paper, label packages for home desktop design and printing. The first version of the software was made by Surething software while the second version the software was made by a different vendor and was coded from scratch.

"Version 2.0 of 3M Printscape(tm) Software was developed to make it easy for you to design and print on 3M Printscape(tm) Products. If you have Version 1.0, 1.01 or 1.5 of 3M Printscape(tm) Software, you do not have to uninstall this software before installing Version 2.0. Version 2.0 will not write over an earlier version.  If you have saved any designs from earlier versions, you will not be able to open them in Version 2.0 because the applications are completely different.  We, therefore, recommend that you keep both the earlier version and Version 2.0 on your computer."
