You can use ShellExecute API #12636.

DECLARE INTEGER ShellExecute IN "Shell32.dll" ;
    INTEGER hwnd, ;
    STRING lpVerb, ;
    STRING lpFile, ;
    STRING lpParameters, ;
    STRING lpDirectory, ;
    LONG nShowCmd

lcPDFfile = "c:\mydir\myfile.pdf"
* Open PDF file
=Shellexecute(0,"Open", lcPDFfile, "","",7)
* Print PDF file
=Shellexecute(0,"Print", lcPDFfile, "","",0)
