To use any of the printing functions select_font(font) must be called with one of the following included fonts or a custom user font set.
When using a locationally aware print function ie print(10,10,"Hello World) the cursor will be left at the end of the print call. So to print the string "My double=" at (10,10) the following can be done:
tv.print(10,10,"My double="); tv.print(somedouble);
Assuming that tv is the instantiated TVout object.
