I use that. It works very well.

SET PRINTER TO myprinter.txt
SET PRINTER on
SET CONSOLE OFF
?"nfdgkfdjkgfk"
?"ncvmxvkcxvkc"
?"kvdjlgjkfsl"
SET PRINTER TO 
SET CONSOLE ON 
SET PRINTER off  

xfile="myprinter.txt"
  STRTOFILE(CPCONVERT(CPCURRENT(1) ,CPCURRENT(2),FILETOSTR(m.xfile)),m.xfile)

DECLARE INTEGER CopyFile IN kernel32;
	STRING lpSrcFile, STRING lpDstFile, INTEGER bFail
CopyFile(m.xfile,m.xport, 0)

also you can do it with reports:

report form myreport to file myprinter.txt ascii

other codes like upper.
