'What is the difference between .lbl and .zpl extension?

I have a code which generates a ZPL file which can be sent directly to a printer or downloaded like a file with a .zpl extension. My question is what is the difference between this .zpl and .lbl extension files? The code for the ZPL is below.

^XA

^FX Top section with logo, name and address.
^CF0,60
^FO210,100^FDCompany Name Here^FS

^FX Second section with item information
^CFA,30
^FO30,300^FDITEM NAME: Printer^FS
^FO30,340^FDSERIAL NO: 12345^FS

^FX Third section with bar code.
^BY4,2,250
^FO100,550^BC^FDsparc123^FS

^XZ

If they are the same does it mean I can change the file extension from .zpl to .lbl and print it without a problem?
