The resolution of the Black Ice printer is set to 100 x 100 DPI in the Device settings tab of the Printing Preferences dialog (the same default resolution I set at installation). Yet, when I run an application, invoke Print, chooses the Black Ice Printer, and brings up its Printing Properties screen, the resolution is almost always something different. (Usually 200x200 or 600x600.) Note that the Black Ice Printer is not installed as the system's default printer. What are we doing wrong?
A printing application always uses the default printer settings for a document. When one tries to print the document to another printer, the printing application uses the settings of the default printer. If the default printer settings are in the range of the destination printer driver device capabilities, then the destination printer uses the settings of the default printer. The user can test this with 2 printers by setting the default printer A to landscape, and the second printer B to portrait mode. Print the document and select the second printer and just print. The second printer prints in landscape mode even though it is configured in portrait mode. The same is true for the Dot Per Inch (DPI) resolution, but it is not visible and sometimes one cannot tell the difference.
