As Chris responded, virtually none of that page is relevant to mspgcc. What you can do with printf depends on how your putchar() is implemented. mspgcc doesn't deliver one since it's board-specific. Check with whoever provided the Z1 putchar() implementation to find out whether you are allowed to invoke printf from interrupt handlers or with interrupts disabled, and other limitations. It's fairly likely that you can't print anything from an interrupt handler. (At one point Zolertia delivered an mspgcc toolchain based on the CPUX branch. If you're using that instead of the current LTS mspgcc, you definitely need to ask them for support. Based on old bug reports, I suspect that version would not handle varargs correctly, especially if you're using its far memory support.)
