虚拟图像打印机驱动
NED Image Driver is a printer driver for Microsoft Windows 2000.
It is installed and it operates like any other printer driver. However,
instead of sending documents to a real printer, it creates a multi-page
TIFF file that you can view with any image viewing application that
supports multi-page TIFF files. This is very useful for developing the
print logic in your own applications. You can debug your print logic without
using a real printer - thus saving lots of paper, time and equipment.
The driver calls a DLL, EXIT32.DLL, that creates the TIFF file. This 32-bit
DLL receives a monochrome or 24BPP color bitmap from the driver. Functions
in the DLL are called at the beginning of a print job, at the beginning of
each page, at the end of each page, and at the end of the print job.
The source code for the EXIT23.DLL, which is written in Miscrosoft Visual C++,
is available from Northeast Data Corp. as an option.
By customizing the DLL, you can redirect print
