First, you will need to realize that most/all applications in Linux print in Postscript format. How the application actually talks to the printing system is through a high-level printing system (e.g. CUPS, which we will discuss below). It is the job of CUPS to provide a standard interface for applications to talk to. CUPS takes the Postscript print files and, if necessary, passes them to a set of low-level drivers (printer dependent) which then converts the data into a language that the printer can understand and sends it to the printer itself.

If your printer supports Postscript format directly then it is unnecessary to install a low-level driver - you can just print the raw files out to the printer in "raw" mode. which is when linux uses the local raw printers which are the printer drivers in linux.
