Pscript-supported escapes
Important
The modern print platform is Windows' preferred means of communicating with printers. We recommend that you use Microsoft's IPP inbox class driver, along with Print Support Apps (PSA), to customize the print experience in Windows 10 and 11 for printer device development.
For more information, see Modern print platform and the Print support app design guide.
The PScript5 printer driver supports the following escapes.
| Escape | Description |
|---|---|
| BEGIN_PATH | Open a path. |
| CHECKJPEGFORMAT | Determine whether a printer can handle a JPEG image. For more information about this escape, see CHECKJPEGFORMAT. This escape produces a call to the DrvQueryDeviceSupport function. |
| CHECKPNGFORMAT | Determine whether a printer can handle a PNG image. For more information about this escape, see CHECKPNGFORMAT. This escape produces a call to the DrvQueryDeviceSupport function. |
| CLIP_TO_PATH | Define a clip region that is bounded by a path. |
| DOWNLOADHEADER | Download all of the procsets (that is, sets of PostScript procedures). |
| DRAWPATTERNRECT | Create a white, grayscale, or solid black rectangle by using the pattern and rule capabilities of Page Control Language (PCL) on Hewlett Packard LaserJet or LaserJet-compatible printers. A grayscale is a gray pattern that contains a specific mixture of black and white pixels. For more information about this escape, see DRAWPATTERNRECT. This escape is associated with the driver's DrvEscape function. |
| ENCAPSULATED_POSTSCRIPT | Send Encapsulated PostScript (EPS) data to the printer. This escape is associated with the driver's DrvDrawEscape function. |
| END_PATH | End a path. |
| EPSPRINTING | Indicate the start or end of EPS printing. The graphics device interface (GDI) intercepts this escape and translates it to a DDI call other than DrvEscape. The printer driver does not receive this escape. |
| GET_PS_FEATURESETTING | Get information about a specified feature setting for a PostScript driver. For more information about this escape, see GET_PS_FEATURESETTING. |
| GETTECHNOLOGY | Get the general technology type for a printer. Printer drivers that are written for versions of the Windows operating system after Windows 3.0 might not support this escape. |
| PASSTHROUGH | Send data directly to a PostScript printer driver in compatibility mode or GDI-centric mode. PostScript printer drivers in PostScript-centric mode do not support this escape. For more information about this escape, see PASSTHROUGH. |
| POSTSCRIPT_DATA | Send data directly to a printer driver. This escape is identical to the PASSTHROUGH escape except that PostScript printer drivers support this escape in Windows NT 4.0 compatibility mode only. For more information about this escape, see POSTSCRIPT_DATA. |
| POSTSCRIPT_IDENTIFY | Set a PostScript printer driver to GDI-centric or PostScript-centric mode. For more information about this escape, see POSTSCRIPT_IDENTIFY. |
| POSTSCRIPT_IGNORE | Suppress output. |
| POSTSCRIPT_INJECTION | Insert a block of raw data in a PostScript job stream. |
| POSTSCRIPT_PASSTHROUGH | Send data directly to a PostScript printer driver in Windows NT 4.0 compatibility mode or PostScript-centric mode. PostScript printer drivers in GDI-centric mode do not support this escape. |
| QUERYESCSUPPORT | Determine whether the device driver implements a particular escape. |
| SETCOPYCOUNT | Set the number of copies to be printed. This escape has been superseded by the DocumentProperties and PrinterProperties functions. |
| SPCLPASSTHROUGH2 | Enable applications to include private procedures and other resources at the document level-save context. For more information about this escape, see SPCLPASSTHROUGH2. |
