This page shows the difference between the conversion effects of using "-useprinter" and not-using "-useprinter" of VeryDOC EMF to Vector Converter. The option "-useprinter" is added in the update of version 3.0.

The first image shows the EMF file that will be converted to PDF for test.

If we use the following commands without option "-useprinter" to convert the EMF to PDF, we will get a blank PDF, which means the conversion is failed.

The command line is as the follow.

This can only create a blank PDF page as shown in the second image below.

Now we will use the option "-useprinter" to convert the EMF to PDF.

Then the PDF will be correctly created as shown in the last image.

Note:

You must run as an Administrator when using the option "-useprinter". The option will create a PostScript virtual printer for converting EMF.
