title: Checking Printer Messages using OPOS Drivers in Delphi
body: <p>I'm trying to open a Point of Sale (POS) printer using the OPOS Drivers in Delphi (BDS2006), but don't have a clue on how to check the printer status.</p>
  
  <p>How would I check for messages like <code>Check Paper</code> and <code>Paper Jam</code> from the printer?</p>
