You should create a subkey within [HKEY_LOCAL_MACHINE\Printers\] to store configuration information for your printer driver. There are four values you should define, Driver, High Quality, Draft Quality, and Color. The Driver value names the dynamic link library that contains your printer driver. The High Quality and Draft Quality values store the resolution of high-quality and draft modes, if the printer you are driving supports them. No matter what modes your printer supports, you should always supply a High Quality value. The Color value defines whether your printer can print in color or only in monochrome.
The following registry (.REG) file excerpt defines settings for the PCL printer driver.
