PRB: GP Fault on DC_BINADJUST if No Input Bins Are Selectable
The information in this article applies to:
- Microsoft Win32 Device Driver Kit (DDK) Windows 95
A printer minidriver may cause a GP Fault when processing DC_BINADJUST (wIndex == 19) if the driver does not create any input bins or does not make any input bins selectable in UniDrv.
The fault occurs when the driver passes the DC_BINADJUST down to UniDrvDeviceCapabilities(). UniDrvDeviceCapabilities() does not check for null string pointers. If no input bins are selected, the bin name strings will be null and a GP Fault will occur.
Printer minidrivers must always create at least one selectable input bin. You can create an input bin in UniTool by selecting Printer Data/Paper Info/Source. To make the bin selectable using UniTool, select Printer Data/Model Data, and make sure at least one bin is enabled for Paper Sources in the list of Supported Attributes.
This behavior is by design.
