If you want text to be wrapped, then you shouldn't be using the printer in graphics mode. Better to just open the printer and print to it, or even just print to the screen an allow the users to redirect to the printer themselves.

If you want to continue to have control over the fonts, paper orientation etc., but allow the user to make choices about these, you are into the whole thing of finding out what printers they have installed, querying their capabilities, offering dialogs for font selection etc. That is lots of work.

It would be much easier to produce your output as html/css (which will take care of wrapping and pagination) to a file and then start the users browser to display it.

From there, the user can override your choices of fonts and so on using a user defined css file and the browser already has all the required smarts to interface with the printers.
