I havneæt used ??? for many years, but I have read many messages about problems with ???. The best solutions seems to be to use a file:

SET PRINTER TO "dummyfile"
??? whatever
??? more whatever
.. other commands to the file
SET PRINTER TO NAME yourprinter
??? filetostr("dummyfile")

>The name is same as I was using. Even better, set printer to worked with the name I am using today!
>HOWEVER, when I try to send a character string that is 70000 char, it gives a syntax error.
>So I typed
>???left(xd,20000)
>???substr(xd,20001,10000)
>and got a syntax error on the second line! ???chr(12) did work.
>Any suggestions here? The printer did print the top of a special letterhead
