Caret file? Do you mean zpl, the actual label to be printed? If so you can access that from the web interface, just point your browser to the printers ip and follow the menu's. If it's not on a network you can use a command prompt the "type" the message to the com port. Just create a text file with the zpl and save it, then in a command prompt browse to the directory that contains the zpl and issue the command "type zpl.txt > com1" or whatever com it's on.
