Print as bitmap

When you print to a non-PostScript printer, you can choose to rasterize all artwork during printing. This option is useful when printing documents that contain complex objects (such as objects with smooth shading or gradients) because it reduces the possibility of errors.

Choose File > Print.
Select Advanced on the left side of the Print dialog box.
Select Print As Bitmap.
This option is available only if the printer driver identifies the printer as non-PostScript. If this option is selected for non-PostScript printers in Mac OS 10.3 or later, InDesign prints PostScript, which is then used by Mac OS and the driver to render the page images. In Windows, the high-end color and graphics features may not be converted appropriately if this option is not selected.
Specify a resolution for bitmap printing.
The output resolution may be limited by the printer driver’s resolution. To get the best quality output, set the non-PostScript printer driver resolution to be equal or greater than the output resolution specified in the InDesign Print dialog box.
