What kind of options do I have regarding printing a document to pdf?

Even though the document I have looks nice on the screen, it doesn't fit to a A4 pdf page.

Are there any scaling options, or fit to page anywhere which I did miss?

Any idea of how to import necessary libraries for use in Maple Player?

Is it possible to draw objects in Maple graphically, that are defined by parameters?

Like rectangles with width and height, circles with a radius, triangles, etc.

Is it possible to check, if a component - like a combobox - exists?

Is it possible to generate a XMLElement by using part of the code to be generated with a string, or are the only methods a strict use of AddAttribute and AddChild?

Hope the code below explains what I mean. The first line is a strict copy of a declaration in the help file.

The question is if I could use some part of the definition which is saved in the str variable and combine it into the first declaration?
