WINDOWS
Summary:
SYMPTOMS
When certain Windows Graphics Device Interface (GDI) functions are
used with a printer device context (DC), the functions do not
affect the printed results.
CAUSE
The printer is a banding device and the application is not
performing banding.
RESOLUTION
Modify the application to perform banding or remove any GDI
functions that are not supported by metafiles. The "Microsoft
Windows Software Development Kit Reference Volume 1" for version
3.0 lists on pages 2-41 and 2-42 the functions that are valid in a
metafile, and the "Microsoft Windows SDK: Programmer's Reference,
Volume 1: Overview," for version 3.1 lists the valid functions on
page 107; however, these lists contain some errors. To obtain an
updated list of valid functions, query on the following words in
the Microsoft Knowledge Base:
prod(winsdk) and metafile and valid and functions
More Information:
When an application prints to a banding device and does not perform
banding, Windows GDI collects all the output function calls and
creates a metafile. During the process of printing, GDI plays this
metafile into each of the bands received from the printer driver. Any
functions that are not supported in metafiles do not work under this
scenario.
For more information on adding banding to an application, query on the
following words in the Microsoft Knowledge Base:
prod(winsdk) and banding and application
Other sources of information are Chapter 12 of the "Microsoft Windows
Software Development Kit Guide to Programming" for version 3.0 and
"Programming Windows" by Charles Petzold (Microsoft Press).
