title: what do i need to print from ipad/iphone?
body: <p>I want my ipad/iphone app to print to a thermal printer (pos printer). It seems there is no airport express compatible thermal printer in the market. I am not sure if I could use a Mac or Windows as a printer server? </p>
  
  <p>If so: 
  1. What kind of configuration do I need to do on iPad &amp; Mac? 
  2. Do I need special software on iPad or Mac/Windows?
  3. Could any USB thermal printer do the job?</p>
  
  <p>Thanks in advance</p>
