Query: Does not print shipping labels!!! WARNING

I bought this product because the advertisements all say "Prints 4x6 Shipping Labels."Once I received this printer, plugged it in, and called tech support, I was informed that while this printer does technically print shipping labels (only for Ebay or Paypal), it does NOT support or print labels through any of the main shipping companies: USPS, USP, or Fed Ex (unless you also subscribe to Endicia for $16 per month). I promptly returned it and called DYMO. Their 4xl printer is the only one I've found that prints typical shipping labels on a Mac computer through the major carriers. (They provide the Endicia software free of charge.) Be forewarned...
