PostScript Pass-Through

PostScript Pass-through provides a workaround for rare cases where certain jobs do not print correctly. Conflicts can occur when using driver features such as booklet layout with an application that uses PostScript Pass-through.

To select PostScript Pass-through options:

On the Advanced tab, click Driver.
Click PostScript Pass-through. Select an option:
- Enabled allows the application to bypass the print driver and directly generate its own PostScript file for the print job. Selecting this option causes the application to overwrite some of the print driver settings.
- Disabled allows the print driver to generate the PostScript file for the job. If you experience compatibility problems, use this setting. Disabled produces reduced print quality, especially for EPS files, compared to the same driver with pass-through enabled.
  Encapsulated PostScript (EPS) produces a single-page .eps file to insert as an image in a document in a different application. The contents of the page can include any combination of text, graphics, and images.
  Create Encapsulated PostScript files in the application for best results. When this method is not possible, select Encapsulated PostScript to set the print driver to create .eps files. Encapsulated PostScript files created by the driver do not include onscreen preview images. An image appears as a blank space, black box, or as a crossed out box placeholder for the image when previewed. However, images appear as expected when printed.
  Note: Not all applications can place Encapsulated PostScript files in their documents. If you experience printing or compatibility problems with some applications, try printing the document with different PostScript settings.
Click OK.
Note: Printing errors can occur when printing a booklet with PostScript Pass-through enabled. Disabling PostScript Pass-through ensures that any document can be printed as a booklet.
When PostScript Pass-through is enabled, the Windows PostScript driver typically cannot create booklets when printing from pass-through applications. The print driver cannot notify the application that it is going to reorder the pages. Therefore, pages must not contain page-dependent PostScript such as reference fonts downloaded for previous pages. Jobs that contain page-dependent PostScript typically fail during Raster Image Processing (RIP). Disabling PostScript Pass-through ensures that any document can be printed as a booklet.
Raster Image Processing (RIP) converts the PostScript or other PDL for a page into a simple bitmap, or raster data. The printer uses the data to draw the pixels on a sheet of paper.
