After you've specified the paper sizes and qualities for your printer, you should specify the paper sources. The following illustration shows the Paper Sources dialog box:
For the Diconix 150 Plus printer, there are two supported paper sources. The following contains the constants used to identify these sources as well as a brief description of the constant.
| Constant | Description |
| DMBIN_TRACTOR | Specifies tractor-feed capabilities. |
| DMBIN_MANUAL | Specifies manual-feed capabilities. |
For the HP LaserJet IIP printer, there are four supported paper sources. The following identifies each.
| Constant | Description |
| DMBIN_UPPER/ONLY | Specifies upper-paper tray capabilities. |
| DMBIN_ENVMANUAL | Specifies manual envelope-feed capabilities. |
| DMBIN_MANUAL | Specifies manual-feed capabilities. |
| DMBIN_LOWER | Specifies lower-paper tray capabilities. |
The examples in the following sections are based on the first paper source that was initialized for each minidriver. In the case of the Diconix, the first paper source specifies tractor-feed data; in the case of the HP LaserJet IIP, the first paper source specifies upper-tray data.
