This document describes MicrosoftÒ WindowsÔ 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, ren-dering bitmaps, or advancing a page).
