printf is a libarary function, while printk is implemented in kernel itself since kernel doesnt use library functions.
printf displays on STD output, while printk logs the messages and kernel log demon displays that content on the screen.
Apart from this, you can also pass the priority of the message to printk.
Hope it helps

Easy: printf() is for userspace, printk() is for kernel space.
