Change print settings that are local to an application

To make changes to print settings that are local to an application, an application should follow these steps:

1. Get the number of bytes required for the full DEVMODE structure by calling DocumentProperties and specifying zero in the fMode parameter.

2. Allocate memory for the full DEVMODE structure.

3. Get the current printer settings by calling DocumentProperties. Pass a pointer to the DEVMODE structure allocated in Step 2 as the pDevModeOutput parameter and specify the DM_OUT_BUFFER value.

4. Modify the appropriate members of the returned DEVMODE structure and indicate which members were changed by setting the corresponding bits in the dmFields member of the DEVMODE.

5. Call DocumentProperties and pass the modified DEVMODE structure back as both the pDevModeInput and pDevModeOutput parameters and specify both the DM_IN_BUFFER and DM_OUT_BUFFER values (which are combined using the OR operator).The DEVMODE structure returned by the third call to DocumentProperties can be used as an argument in a call to the CreateDC function.

To create a handle to a printer-device context using the current printer settings, you only need to call DocumentProperties twice, as described above. The first call gets the size of the full DEVMODE and the second call initializes the DEVMODE with the current printer settings. Pass the initialized DEVMODE to CreateDC to obtain the handle to the printer device context.
