I'm having troubles with this, I managed to set the size of the pdf document to the one I needed (~3cm x ~7cm), but the content inside the pdf is using like a third of the space. And I need to use the whole available space.
So, this is how it looks:

See how all the content is centered in that little space in the middle. I tried setting the table widthpercentage to 100, with no luck.
What can I do?
