I copy and paste from the Nios SW Developer's handbook: 

alt_printf()
This function is similar to printf(), but supports only the %c, %s, %x, and %%
substitution strings. alt_printf() takes up substantially less code space than
printf(), regardless whether you select the lightweight device driver API.
alt_printf() occupies less than 1Kbyte with compiler optimization level -O2.
