title: Print to a UPS / Fedex Thermal printer?
body: <p>I have a client asking if their web application (PHP) can easily print to a UPS / Fedex thermal label printer. </p>
  
  <p>So for instance, I can get back a PDF from UPS/Fedex with the shipping label. I just need to print that. </p>
  
  <p>Does anyone know if you can print directly to these printers or, if not, if there's another way to do it? </p>
  
  <p>EDIT: To clarify, all I want to accomplish is to be able to print to these printers, without having to make my client ALT-TAB to some third-party application like UPS Worldship or ShipRush or QuickBooks Shipping Manager and clicking 'Print' within that application. Do-able?</p>
