The Generic Text Only driver (see screenshot below) is a native Microsoft printer driver. We have seen multiple attempts by Microsoft to remove this from Windows distributions. Unfortunately, we have no means or knowledge of how to add this driver when it is missing in your version of Windows.
This driver is typically used only in older printers that do not support either FGL or PCL drivers. This driver does not support WYSIWYG, true type fonts, or graphics.

We generally advise avoiding the use of this driver whenever possible, as Microsoft support for it is becoming increasingly difficult with each version of Windows. Microsoft plans to discontinue their usage of third party printer drivers over the next few years. In consideration of this, we have developed Windows, Mac and Linux SDKs to provide our customers with the opportunity to make a smooth transition to the new driverless platform.
All SDK’s support printing from bmp, jpeg and png files. HTML and pdf support have been added to the Windows SDK.
The SDK’s can be found here: Sample code and SDK
