Printer is by default class library for handling the printing stuff from the VB
code. You don't need any extra dll to use. To my knowledge, most of the work can be accomplished by this printer object.
Printer.Orientation = vbPRORPortrait OR vbPRORLandscape
CONSTANTS (by default, use as needed)
vbPRORPortrait = 1
vbPRORLandscape = 2
