Color Support in Windows Printer Driver

ID: Q141208

The information in this article applies to:

• Microsoft Windows 95 Device Driver Kit (DDK)

SUMMARY

A Windows 95 print driver is capable of rendering images into a 4-, 8-, 16-, 24-, or 32-bits-per-pixel Device Independent Bitmap format.

MORE INFORMATION

In order to support rendering of images up to 32-bits-per-pixel, UNIDRV.DLL uses the services provided by the DIBENGINE.DLL shipped with the Microsoft Windows 95 Operating system. This can be specified by specifying the number of planes in the sPlanes box as 1 and sBitPixel as 4, 8, 16, 24, or 32.

However, if you choose to use the planar model sPlanes > 1, UNIDRV.DLL uses the DMCOLOR.DLL shipped with the Microsoft Windows 95 operating system. DMCOLOR.DLL supports RGB format and, therefore, the bitmap is 3 planes with 1 bit-per-pixel.
