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/.docx documents may contain lots of raster data. Adobe .pdf files and Word .doc/.docx documents that contain gradients are even more likely to contain lots of raster data.
This problem occurs because Graphics Device Interface (GDI)
does not compress raster data when the GDI processes EMF spool
files and generates EMF spool
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.
To resolve this problem, bypass EMF spooling. To do this, follow these steps:
- Open the properties dialog box for the printer.
- Click the Advanced tab.
- Click the Print directly to the printer option.
Note This will disable all print processor-based features such as
the following features:
- Booklet printing
- Driver collation
Once EMF spooling is turned off, you can use the Application to perform any N-up printing needed.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the “Applies to” section.
