Port help

[biferi]

I think I understand how Parallel Ports work can someone tell me if I am right??

All Parallel Ports are 1. Byte Data Width.

Now
Parallel Port 1. can just send 50 kBp Output

Parallel Port 2. can have 4. Bit Input called Nibble but it still di only 50 kBps Output RIGHT amd I right so far???????

Parallel Port 3. can do 1. Byte Input called BYTE Mode and sent Data at 150 kBps

am I right???
