The MPERIA plugin script is able to be configured with multiple print streams that can additionally be configured to print on one or more print heads.

A stream is what we have called a print message in the past.

If the same stream is supposed to print on both sides of a part, it may have assembly marks and text to indicate where other parts line up to the part being produced. In order for the text an and assembly marks to be legible, each text string must be individually rotated 180 degrees to that the string is still readable.

For Example, if a | image is placed on the part to indicate a location on the part it may have some text like "ABC" that indicates which other part is supposed to join at the | image location. On one side of the part the A must be printed first to be readable. On the other side the C must be printed first to be readable.

The script has been modified to internally and optionally rotate all print objects within one print stream for only one of multiple heads.
