Introduction

This document describes Microsoft(R) Windows(TM) UniTool--a new
printer-driver development tool which you use to create a Windows printer
driver that uses the Microsoft Windows Universal Printer Driver
dynamic-link library (UNIDRV.DLL). The printer driver, referred to as a
minidriver, contains data which describes the printer's capabilities,
commands, and its resident fonts. The code in a minidriver forwards
graphics device interface (GDI) calls to the Universal Printer Driver. The
Universal Printer Driver carries out the appropriate actions on the device
(such as printing text, rendering bitmaps, or advancing a page).
