Try the following to print all pictures into Powerpoint with one command:
1. In Testlab, choose "File -> Printing Options". Set Office application to Powerpoint and set the mode to Electronic rather than paper.
2. Then choose "File -> Print" from the main menu. A prompt will appear for the directory and name for the powerpoint file to be created in.
3. In the powerpoint, each picture layout (frontback, colormap, etc) is one page in the resulting powerpoint.
To control the appearance in powerpoint (add logo, change size) see Testlab Format based printing with Powerpoint knowledge base article.
Hope that helps!
One quick tip when doing the format based printing. After generating the format with the "Make Printformat...", be sure to remove the current data from the format (right click and remove the data).
If you don't, your format will have data in it already, and any new data will be plotted on top of it. Best to have a clean empty format. Screenshot below.
