if (AddForm(hPrinter, 1, (BYTE*) &FormInfo))
{
FillPrinterPapers();

{
DWORD dwNeeded = 0;

GetPrinter(hPrinter, 2, NULL, 0, &dwNeeded);
if (dwNeeded > 0)
{
BYTE* lpPrinterInfo = new BYTE[dwNeeded];

// get current printer settings
if (GetPrinter(hPrinter, 2, lpPrinterInfo, dwNeeded, &dwNeeded))
{
DEVMODE* lpDevMode = ((PRINTER_INFO_2*) lpPrinterInfo)->lpDevMode;
lpDevMode->dmFields = lpDevMode->dmFields|DM_ORIENTATION |DM_PRINTQUALITY|DM_YRESOLUTION;

// change parameters
lpDevMode->dmOrientation = 1;    // Orientation: 1 - portrait; 2 - landscape.
lpDevMode->dmPrintQuality = 300; // Horizontal resolution value
lpDevMode->dmYResoultion = 300; // Vertical resoultion value
