To make printer driver installation easier and more intuitive, printer-model names have been removed from the DeviceMode dialog box. Users have found it confusing to select a printer model when installing the driver only to have to reselect the printer model again within the printer's DeviceMode dialog box. For Windows 3.1, the DeviceMode dialog box displays the name of the printer model (selected during installation by the user) in the title bar of the dialog box.
To support this change, printer drivers must now have corresponding SETUP.INF or OEMSETUP.INF entries that list all the printer-model names. Control Panel uses the entries to determine which printer models are available. If the entries aren't available, Control Panel obtains the printer-model name from the DESCRIPTION statement in the driver's executable file header.
