Optimizing Printing

The PrGeneral procedure helps you achieve the highest possible resolution on the current printer, verify page orientation, and force enhanced draft-quality printing for printer drivers supporting these options. To select which action you want, pass one of four records to PrGeneral and, in a field of that record, you supply the opcode that specifies the action you require. These records are TGetRslBlk (described on page 9-50), TSetRslBlk (described on page 9-51), TGetRotnBlk (described on page 9-53), and TDftBitsBlk (described on page 9-52). All of these records are based on the TGnlData record (described on page 9-49), so the first three fields of each are identical.
