Download KONICA MINOLTA mc2530DL(unidrv) for Windows to printer driver. Installing a Unidrv Minidriver.; 2 minutes to read; b; In this article. Installation of a Unidrv minidriver requires a printer INF file that identifies the minidriver's files. If a printer model is not supported by Microsoft's printer INF file, ntprint.inf, a vendor-supplied INF file is required.

UniDrv (Universal Printer Driver or Unidriver) is a GDI-based Microsoft Windows universal printerdriver and architecture for non-PostScript printers. It is used to simplify driver development of non-PostScript printers (also called Winprinters) for printer manufacturers. Unidrv allows the creation of a printer-specific minidriver in the form of a GPD (Generic Printer Description) file, similar to a PPD file, which is much simpler than kernel mode driver development. Unidrv was introduced in Windows 2000 and replaced the Raster Device Driver (RASDD) interface used in Windows NT 4.0 and earlier versions.

Overview[edit]

The concept behind Unidrv is that a complete printer driver need not be written by the hardware manufacturer; only a device-specific minidriver is required that uses the core printing functionality of the Unidrv engine. A minidriver can be a customization file, or a plug-in, that allows special rendering functions or customized UI options. Unidrv supports non-PostScript printers driven by PCL and PCL-like page description languages.

Driver file details[edit]

The Unidriver is implemented as a set of DLL and GPD files along with other printer-specific support files:

• UniDrv.dll is the printer graphics driver file for printer languages based on raster images, including most inkjet and dot-matrixprinter languages.
• UniDrvUI.dll is the configuration file. It displays the user interface for UniDrv.dll.
• UniRes.dll, StdNames.gpd, TtfSub.gpd and some other support files.
• Raster minidriver, which has the file name extension .GPD, is the data file, and is also called the characterization file. The file name depends on the printer or printer family.

Newer Unidrv-based printer drivers from some printer vendors, e.g. Hewlett Packard, may contain many other support files to allow support for more printer-specific options.

Unidrv capabilities[edit]

The Unidriver is also called the raster driver because it supports raster (bitmap) graphics printing and is compatible with many printers. This driver supports the following features:

• Color printing at various depths, such as 4 bits per pixel (bpp), 8 bpp, and 24 bpp.
• Scalable TrueType and OpenType fonts, device fonts (including double-byte), grayscale printing, font substitution, run length encoding (RLE), Tag Image File Format (TIFF) version 4.0, and Delta Row Compression (DRC).
• An extension interface that allows printer manufacturers to extend and customize the driver for specific models.
• Vector graphics languages HP-GL/2 and PCL-XL, monochrome, and color.

Determining if the printer driver is Unidrv-based[edit]

To determine whether a driver is Unidrv-based, the following steps need to be taken on Windows:

1. Click the Start button, and then open the Printers folder.
2. From the File menu, click Server Properties.
3. Click the Drivers tab.
4. Select a driver, and then click Properties.
5. Observe the driver list in the Driver Properties dialog box. If UniDrv.dll appears on the list of files, the driver is Unidrv-based.

Future[edit]

Starting with Windows Vista, Unidrv is intended to be succeeded by XPSDrv. The XPSDrv printer driver extends Microsoft's GDI-based, printer driver architecture to support consuming XML Paper Specification (XPS) documents and is more modular and extensible. With an XPSDrv printer driver, the XPS Document format is used as a spool file format and as a document file format.

References[edit]

Errors related to unidrv.dll can arise for a few different different reasons. For instance, a faulty application, unidrv.dll has been deleted or misplaced, corrupted by malicious software present on your PC or a damaged Windows registry.

The most commonly occurring error messages are:

• The program can't start because unidrv.dll is missing from your computer. Try reinstalling the program to fix this problem.
• There was a problem starting unidrv.dll. The specified module could not be found.
• Error loading unidrv.dll. The specified module could not be found.
• The code execution cannot proceed because unidrv.dll was not found. Reinstalling the program may fix this problem.
• unidrv.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vender for support.

Unidrv Dll File Missing

In the vast majority of cases, the solution is to properly reinstall unidrv.dll on your PC, to the Windows system folder. Alternatively, some programs, notably PC games, require that the DLL file is placed in the game/application installation folder.
