It all depends on what part you want to be simple, the source code or
the object code.

Using 'printf' makes the source code much simpler, easier to read and
usually directly portable between platforms.

I see people using 'printchar', 'printstring', printnumber', etc
functions. Although they may think it makes the code simpler, the source
code becomes much less readable, and sometimes even the object code
becomes less compact than using 'printf'.

Yes, 'printf' is sometimes a behemoth, but I prefer using it because my
code gets more 'normal', and I can port it across several platforms. I
have products that the same source code runs on a PIC18, on a desktop PC
and also on an ARM9.
