The STEVAL-IPC002V1demonstration board is a 
battery-operated hand-held parking ticket vending 
machine system with a thermal printer interfaced 
with the STM32.

The objective of this demonstration is to generate 
and print parking tickets for different types of 
vehicles. The system can be easily modified for 
other applications that require paper printing 
directly from the microcontroller, such as PoS-
based applications, railway/bus ticket printing and 
stand-alone printers.
