There are several known printing issues addressed by the Compatibility Administrator using compatibility fixes and compatibility modes.

Fix Name Symptom Fix Description

Fix Name	Symptom	Fix Description
EmulatePrinter	You receive an access violation error message when the application starts or searches for printers.	Emulates the behavior of the Microsoft Windows®°95 operating system and the Microsoft Windows®°98 operating system to compensate for a variety of differences in the printer functions in Windows XP Professional. Most of the problems are due to differences in the `EnumPrinters` function from Windows 95, Windows 98, to Windows XP Professional.
ForceAnsiWindowProc	The application shuts down unexpectedly when you attempt to print.	Modifies the `GetWindowLongA(GWL_WNDPROC)` function to redirect the `GetWindowLongW` function calls to retrieve the `GWL_WNDPROC` value. This compatibility fix forces the true window procedure address to always be supplied. This fix also works correctly with the `DWL_DLGPROC` value.
