Report to Microsoft PDF Printer creates text as images.

We have a customer who when printing a particular report from a Visual Foxpro application sometimes selects the Microsoft PDF Printer (installed with MS Office). This then prompts for a PDF file to save the report output to. They then open the PDF in Acrobat Reader or whatever and need to select and copy some text from it.

The problem is that sometimes the PDF is rendered as an image so no individual elements are selectable in Acrobat Reader. All fonts on the layout are standard Arial. There are no settings on the PDF printer to adjust and nothing on the VFP side that I can see would affect it.

Replicating this process with the report layouts in question on my PC works fine.

Has anyone ever come across this ?
