SYMPTOMS
When you print a document that contains lots of raster data, the size of the Enhanced Metafile (EMF) spool file may become very large. Files such as Adobe .pdf files or Microsoft Word .doc documents may contain lots of raster data. Adobe .pdf files and Word .doc documents that contain gradients are even more likely to contain lots of raster data.



CAUSE
This problem occurs because Graphics Device Interface (GDI) does not compress raster data when the GDI processes EMF spool files and generates EMF spool files.

This problem is very prominent with printers that support higher resolutions. The size of the raster data increases by four times if the dots-per-inch (dpi) in the file increases by two times. For example, a .pdf file of 1 megabyte (MB) may generate an EMF spool file of 500 MB. Therefore, you may notice that the printing process decreases in performance.



RESOLUTION
To resolve this problem, bypass EMF spooling. To do this, follow these steps:
 * 1) Open the properties dialog box for the printer.
 * 2) Click the Advanced tab.
 * 3) Click the Print directly to the printer option.

Note This will disable all print processor-based features such as the following features:
 * N-up
 * Watermark
 * Booklet printing
 * Driver collation
 * Scale-to-fit



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



Steps to reproduce the problem

 * 1) Open the properties dialog box for any inbox printer.
 * 2) Click the Advanced tab.
 * 3) Make sure that the Print directly to the printer option is not selected.
 * 4) Click to select the Keep printed documents check box.
 * 5) Print an Adobe .pdf document that contains many groups of raster data.
 * 6) Check the size of the EMF spool file.
