It's all in the DevMode.
Use DocumentProperties() 3 times:

1)With NULL for DevMode to get the size of the DEVMODE that you need.
num_bytes=DocumentProperties(NULL,printerHandle,&printerfile_port,NULL,NULL,0);
1a) Allocate a DEVMODE of that size.

2)Again, with the address of your newly allocated DevMode to get the
capabilities.
DocumentProperties(NULL,printerHandle,&printerfile_port,DevMode,NULL,DM_OUT_BUFFER);
2a)Check the bit patterns in  DevMode->dmFields for supported options.
2b)Set the various dmWhatever to single sided, B&W, etc.

3)Last time with the modified DevMode.
DocumentProperties(NULL,printerHandle,&printerfile_port,DevMode,DevMode,DM_OUT_BUFFER|DM_IN_BUFFER);

4)Then, use the returned DevMode from the 3rd call to create the
Printer DC that you will actually print on.

printerDC = CreateDC( NULL, &printerfile_port, NULL, DevMode);
