Then I guess it will work. I appreciate your help. I wrote the code as follows:

* Print the pdf.
llprintpdf = thisform.printpdf(lcxfdf)
IF !llprintpdf 
  * Cannot print the file.
	SELECT(lnalias)
	RETURN .f.
ENDIF

* Wait 12 seconds.
WAIT 'Printing the 8655 form...' window timeout 12
WAIT CLEAR 
	 
lnfilehandle = -1
DO while lnfilehandle == -1
   * Are we finished printing?
   * If we're still printing, we won't be able to open the file r/w.
   * If we're done printing, we can open the file r/w and we will get a reference back to it,
   * the file handle.
   	   
   * Try to open the file open read/write.
   lnfilehandle = FOPEN(lcxfdf,12)  
ENDDO 
   
* Close the file and go.
=FCLOSE(lnfilehandle)
