c - void* for multiple types

Question

Is the following considered bad practice in C?

void (* print_function) (void *obj);

Item1 *item1 = & (Item1) {.id=123};
print_function = print_item1;
print_function(item1);

Item2 *item2 = & (Item1) {.guid="X1-283"};
print_function = print_item2;
print_function(item2);

That is, trying to pass different objects multiple places by using void *? If so, why?
