When APD is used for your existing application
Use APD.
When OPOS ADK is used for your existing application
Use OPOS ADK.
You can use all functions including ones not supported by OPOS ADK or APD by using a
driver with ESC/POS command. Use the DIRECT I/O function of OPOS ADK, the control A
command of APD, or Status API to send ESC/POS command from each driver. (See
"ESC/POS command functions" on page 58
.)
