You can't use 'nor' instead of 'or' in this case, because it can't be rewritten in the 'neither... nor' form, right?

Yes, you can use 'nor' in that case though more often people just say 'or'.

You could re-write it as 'neither...nor'.

'This message should neither be printed nor transfered.' It's a bit bureaucratic sounding.
Thanks Wanwo

Grammartically, either way is okay in my sentence?

You can either say not/or OR neither/ nor. You cannot grammatically use not and nor OR neither and or.
