There seems to be some subtle differences between PS and PCL printer drivers. I would like to know if there is a benefit to using PCL drivers over PS. The network admins I have followed usually had installed PCL drivers on the networked printers. I have found that some things don't work correctly if PCL drivers are used, but the problems go away with PS drivers. I have yet to see PS drivers not print something that PCL can.
So the question is, if both PS and PCL drivers are offered by HP and others, why are so many admins using PCL drivers?
