[Scilab-users] How to print GUI window?

[Samuel Gougeon]

Hello Philipp, hello Ted,

Yesterday evening, I got aware of two important drawbacks of using 
Irfanview, despite its numerous and  huge assets and qualities:

  * It runs only on Windows
  * It is free only for non-commercial usages

...in addition to the fact that it must be installed (trivial, but OK).

These restrictions made me wondering about a more portable solution.
And gui2bitmap() is born :-) http://atoms.scilab.org/toolboxes/gui2bitmap

The printing is also worth considering.
I should have a look later to this matter, for instance to see if it is 
possible
and then how to print directly the snapshot with gui2bitmap, instead of
keeping an image file.
The discussion with Ted made me aware that presently Scilab seems not
able to send any image to a printer. This is a missing feature.

Best regards
Samuel
