Page Layout ⇒ Text Height for thermal Printer (Paper Roll Type)

[verbunk]

Hey Guys,

I'm trying to do a project that spits out some generic header, a generated bit of text in the middle and a closer that would be printed on a thermal, paper roll type, printer. My problem is figuring out the text height ahead of time so that I can get the part of the roll I'm printing on dimensions correctly laid out.

Example. I run the script, it builds a DVI/PDF that has 120 lines in it (excluding the header and footer) how do I make that paper size?
