You must create the PDFCreator object first. Then make it your default printer so you want to store your current default printer. However, if your program fails unexpectedly your default printer will be stuck on the PDFCreator. At least with the version I used.

oPDFJob = CREATEOBJECT("PDFCreator.clsPDFCreator", "PDFCreator_")
oPDFJob.cStart("/NoProcessingAtStart")
OldPrinter = oPDFJob.cDefaultPrinter
oPDFJob.cVisible = .F.
oPDFJob.cDefaultPrinter = "PDFCreator"

Here is how to create the document

WITH PDFJob
                     .cClearCache
	.cVisible = .F.
	.cStart("/NoProcessingAtStart")
	.cOption("StartStandardProgram") = 0
	.cOption("StandardAuthor") = “JOHN DOE” **Optional
	.cOption("StandardTitle") = <FILE NAME> **Optional
	.cOption("StandardSubject") = <File Subject> **Optional
	.cOption("AutosaveStartStandardProgram") = 0
	.cOption("ShowAnimation") = 0
	.cOption("UseStandardAuthor") = 1
	.cOption("UseAutosave") = 1  && 0=PDF
	.cOption("UseAutosaveDirectory") = 1
	.cOption("AutosaveDirectory") = newDir &&Directory to store pdf in
	.cOption("AutosaveFilename") = sTitle  &&Name of the file you want to save
	.cOption("AutosaveFormat") = 0
	.cPrinterStop = .F.
	.cPrintFile(ADDBS(SYS(2023))+"c:\document.doc")  &&Name of the doc you want to convert
ENDWITH

Then I usually reset all the options back to default when finished

*** SET ALL DEFAULTS BACK TO NORMAL ***
WITH PDFJob
	.cDefaultPrinter = OldPrinter
	.cStart("/NoProcessingAtStart")
	.cOption("StartStandardProgram") = pdfjob.cStandardOptions.StartStandardProgram
	.cOption("StandardAuthor") = pdfjob.cStandardOptions.StandardAuthor
	.cOption("StandardTitle") = pdfjob.cStandardOptions.StandardTitle
	.cOption("StandardSubject") = pdfjob.cStandardOptions.StandardSubject
	.cOption("AutosaveStartStandardProgram") = pdfjob.cStandardOptions.AutosaveStartStandardProgram
	.cOption("ShowAnimation") = pdfjob.cStandardOptions.ShowAnimation
	.cOption("UseStandardAuthor") = pdfjob.cStandardOptions.UseStandardAuthor
	.cOption("UseAutosave") = pdfjob.cStandardOptions.UseAutoSave
	.cOption("UseAutosaveDirectory") = pdfjob.cStandardOptions.UseAutosaveDirectory
	.cOption("AutosaveDirectory") = pdfjob.cStandardOptions.AutosaveDirectory
	.cOption("AutosaveFilename") = pdfjob.cStandardOptions.AutosaveFileName
	.cOption("AutosaveFormat") = pdfjob.cStandardOptions.AutosaveFormat
	.cPrinterStop = pdfjob.cStandardOptions.PrinterStop
	.cVisible = .T.
	.cStart(pdfjob.cStandardOptions.NoProcessingAtStartup)
	.cClose()
ENDWITH
RELEASE PDFJob

That should be about it. Hope this helps.
