i tried with a simple example within VFP9
( simple report with just some fields of Text in Arial,Times,MS Sans Serif with different sizes)

PUBLIC loListener
loListener = CREATEOBJECT("ReportListener")
loListener.ListenerType= 0
loListener.PrintJobName = "Test Ohne Listener"
REPORT FORM fonttest NEXT 1 TO PRINTER PROMPT NOCONSOLE NODIALOG
loListener.PrintJobName = "Test Mit Listener"
REPORT FORM fonttest NEXT 1 TO PRINTER PROMPT NOCONSOLE NODIALOG OBJECT loListener


Report 1 generates a PDF with embedded Fonts
Report 2 generates a PDF but all Text are Bitmaps

Problem 1: - if u dont use Highest Image Quality u get really granular Text
Problem 2: with Win2pdf Version <= 2.80 most Text have black,Bold stripes over the Text ( worked with win2pdf 2.88 [beta] )

is where some settings to handle the generation [ e.g. setting to deciede if VFP should convert Text Fonts to Text Bitmaps !?]
