thanks for your time.
sorry, but this answer is too basic and elementary.
i reached a mac computer tech yesterday, and they advised me to reinstall my 10.5.8 operating system, in order to repair the missing printer commands.
This question/problem was resolved last week after I reinstalled my operating system on my MAC computer. The printer driver software was fine and installed correctly. I was missing some files in my operating system, which the new install fixed automatically.
Everything is working fine now.
No need to answer any other questions about this past issue.
