Application Development Information
This chapter describes how to control the printer and gives information useful for printer
application development.
How to Control the Printer
Use a driver or ESC/POS commands to control the printer.
Selecting a Driver
Choose one of the drivers, Advanced Printer Driver (APD) or OPOS ADK, depending on the
application operating environment. You cannot control the same printer with both of the drivers.
For information about the driver operating environment, see the installation manual for each
driver.
When you newly develop an application
•Use APD if you want to print TrueType fonts or print much graphics.
•OPOS ADK is recommended for system extensibility. A n OPOS driver is provided for various
peripherals and it is now a POS industry standard. It enables efficient POS system
establishment, reduction of development cost
, and effective use of application assets.
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 commands. Use the DIRECT I/O function of OPOS ADK, the control
A command of APD, or Status API to send ESC/POS commands from each driver. (See
"ESC/POS command functions" on page 52.)
