is the actual tiff already truncated or does this happen in the second step when the .tiff gets converted to PDF?
If the .tiff is still ok but the PDF is missing content, this can be most likely be fixed by using the “run script” action instead of the “print file” action.
A different approach to this would be possible by telling Ghostscript (this is what PDFCreator uses internally to convert the print data to PDF) to not output any fonts. This is a bit experimental though (I have never really tried it) and might produce very large PDF files. If you’d like to try, first close PDFCreator, then open regedit.exe and navigate to HKEY_CURRENT_USER\SOFTWARE\pdfforge\PDFCreator\Settings\ConversionProfiles\0\Ghostscript (where 0 is the default profile) and insert -dNoOutputFonts as value for “AdditionalGsParameters”.
Regarding the font license, most likely you will need to find the font’s owner / distributor and ask them for a licensed version of the font which allows embedding, or find a font with identical metrics and use that as substitution.
