Question:

When printing multiple documents to the Win2PDF printer, some documents are merged together.  How do I prevent this?

Answer:

Win2PDF includes a feature named "Auto-merge" that automatically merges documents with the same title that are sent to the Win2PDF printer in a short period of time.  This is helpful when printing worksheets from Microsoft Excel, but can cause problems in other reporting software.  To disable the feature, download and install the free Win2PDF Admin Utility here:

After installing the Admin Utility, run it and click on the "Troubleshooting" tab.  Change the "Auto Merge Interval" value to 0, and then click "Apply".  If you print to the Win2PDF printer again, it will not longer automatically merge documents.
