UniDrv (Common Printer Driver or Unidriver) is a GDI-based mostly Microsoft Windows universal printer driver and structure for non-PostScript printers. Unidrv was introduced in Home windows 2000 and changed the Raster Machine Driver (RASDD) interface utilized in Windows NT 4.0 and earlier variations. It is used to simplify driver growth of non-PostScript printers (additionally referred to as Winprinters) for printer manufacturers. Unidrv allows the creation of a printer-specific minidriver in the type of a GPD (Generic Printer Description) file, much like a PPD file, which is far less complicated than kernel mode driver growth.

Overview
[edit]
The idea behind Unidrv is that a whole printer driver want not be written by the hardware producer; solely a gadget-specific minidriver is required that makes use of the core printing performance of the Unidrv engine. Unidrv supports non-PostScript printers pushed by PCL. A minidriver can be a customization file, or a plug-in, that permits special rendering functions or custom-made UI choices. PCL-like page description languages.

Driver file particulars
[edit]
The Unidriver is carried out as a set of DLL and GPD information along with different printer-specific help information:

UniDrv.dll is the printer graphics driver file for printer languages primarily based on raster graphics, together with most inkjet and dot matrix printer languages.

UniDrvUI.dll is the configuration file. It shows the person interface for UniDrv.dll.

UniRes.dll, StdNames.gpd, TtfSub.gpd and some other assist recordsdata.

Raster minidriver, which has the file title extension .GPD, is the info file, and can be called the characterization file. The file name depends on the printer or printer household.

Newer Unidrv-primarily based printer drivers from some printer vendors, e.g. Hewlett-Packard, could contain many other support recordsdata to permit help for more printer-particular choices.

Unidrv capabilities
[edit]
The Unidriver can be referred to as the raster driver as a result of it supports raster (bitmap) graphics printing and is compatible with many printers. This driver supports the next features:

Color printing at numerous depths, reminiscent of 4 bits per pixel (bpp), eight bpp, and 24 bpp.

Scalable TrueType and OpenType fonts, system fonts (including double-byte), grayscale printing, font substitution, run-size encoding (RLE), Tag Picture File Format (TIFF) version 4.0, and Delta Row Compression (DRC). Customize the driver for specific models. An extension interface that permits printer manufacturers to increase.

Vector graphics languages HP-GL/2 and PCL-XL, monochrome, and shade.

Figuring out if the printer driver is Unidrv-based mostly
[edit]
To find out whether a driver is Unidrv-based mostly, the following steps need to be taken on Windows:

Click the beginning button, after which open the Printers folder.

From the File menu, click Server Properties.

Click the Drivers tab.

Choose a driver, after which click on Properties.

Observe the driver checklist in the Driver Properties dialog box. If UniDrv.dll seems on the record of recordsdata, the driver is Unidrv-primarily based.

Future
[edit]
Beginning with Windows Vista, Microsoft intends XPSDrv to succeed Unidrv. The XPSDrv printer driver extends Microsoft’s GDI-primarily based, printer driver structure to assist consuming Open XML Paper Specification (XPS) paperwork and is more modular and extensible. With an XPSDrv printer driver, the XPS Doc format is used as a spool file format and as a document file format.
