The following demo was submitted by Robert McAllister ( - 
robmcal ). Use this code to incorporate a look alike printer dialog window in your program. It is setup to work with any DPI setting but that portion can be easily removed if desired. Also, since these functions only work on 2000/XP on up, it checks what platform the program is running on.
It has also been noted by Stefan Pendl ( -
stpendl ) that there is no need to scale native LB controls in a dialog window, since dialog windows are automatically scaled to dpi by Liberty BASIC. API created controls must be scaled manually, even in a dialog window.
