如果打印机支持其他纸张规格，可以通过在打印机驱动程序的 GPD 文件中对其进行描述，将它们添加到 Unidrv 打印机驱动程序。If your printer supports additional forms, you can add them to your Unidrv printer driver by describing them in the GPD file for the printer driver. 如果使用具有 rcNameId 字段的资源 ID * 和用于窗体显示名称字符串的资源 DLL，则驱动程序将自动使用 Windows Vista Unidrv 打印机驱动程序提供的新本地化增强功能。If you use a resource ID with the *rcNameId field and a resource DLL for the form display name string, your driver will automatically use the new localization enhancements features that the Windows Vista Unidrv printer driver provides. Unidrv 打印机驱动程序插件还会自动受益于对后台处理程序所做的更改，无需任何其他修改。Unidrv printer driver plug-ins also benefit from these changes to the spooler automatically and do not require any additional modifications. For more information about these enhancements, see Changes to Printer Forms in Windows Vista.
如果未对 GPD 文件中的可本地化字符串使用资源 DLL，则应删除可本地化的字符串，将它们存储在资源 DLL 中，并将字符串替换为 GPD 文件中的相应资源 ID。If you are not using a resource DLL for the localizable strings in the GPD file, you should remove the localizable strings, store them in a resource DLL, and replace the strings with the corresponding resource ID in the GPD file.
下面的代码示例摘自 GPD 文件，该文件使用显示名称的资源 ID。The following code example is an excerpt from a GPD file that uses a resource ID for the display name.
*Feature: PaperSize
{
*Option: Option2
{
*rcNameID: 259

}
(other form definitions).

在随 Windows Vista 一起提供的 Unidrv 打印机驱动程序中，表单 _ INFO _ 2 结构由从 GPD 文件中读取的数据进行填充，如下表所示。Inside the Unidrv printer driver that is provided with Windows Vista, the FORM_INFO_2 structure is populated by data that is read from the GPD file, as the following table shows. 如果打印机的 GPD 文件中已包含填充此结构所需的信息，则无需更改任何内容即可使用 Windows Vista Unidrv 打印机驱动程序提供的新功能。If the GPD file for your printer already contains the information that is required to fill in this structure, you do not need to change anything to use the new features that the Windows Vista Unidrv printer driver provides.

STRING_MUIDLLSTRING_MUIDLL
如果 GPD 使用 \* rcNameId 选项，并且可以从资源 DLL 中获取窗体名称，则会分配 STRING_MUIDLL 值。If the GPD uses the \*rcNameId option and the form name is available from the resource DLL, the STRING_MUIDLL value is assigned. 如果改为在 GPD 文件中使用 \* rcName 选项，则 STRING_NONE 此字段的值。If the \*rcName option is used in the GPD file instead, the value for this field is STRING_NONE. GPD 文件中的值不用于此字段。A value from the GPD file is not used for this field.

pMuiDllpMuiDll
如果使用 \* rcNameId 选项，则为 GPD 文件中的 \* ResourceDLL 项的值。The value of the \*ResourceDLL entry in GPD file if the \*rcNameId option is used. 如果改为在 GPD 文件中使用 \* rcName 选项，则此字段的值为 NULL。If the \*rcName option is used in the GPD file instead, the value for this field is NULL.
