The HINTS line consists of a single number that determines the preferred duplex printing mode. The HINTS line can have one of the following values, which you cannot override in the Print dialog box.
| Value | Description |
|---|---|
| 0 | No preference |
| 1 | Long side duplex |
| 2 | Short side duplex |
The HINTS line should be set to 0 for formats that have only a single virtual page, 2 for formats specified in LANDSCAPE mode, and 1 for all other formats.
See the example in the Header section for the correct syntax.
