Probably there are spaces in the Printer name. Try to set the default printer first:

oWSHNet = CREATEOBJECT('Wscript.Network')
oWSHNet.SetDefaultPrinter('WindowsPrinterName')

=ShellExecute(0, "Printto", @lc_file, "", 0,1)

Also:
=ShellExecute(0, "Printto", @lc_file, ["]+SET('PRINTER', 3)+["], 0,1)

Double quotes " only work.
