One can always disable Postscript pass-through within the printer driver in situations where this is a problem. The upside is that application release time from clicking print is improved however, this may come at the cost of compatibility with the printer. These applications will often recognize that the driver is Postscript and allow for the application to generate the Postscript output and not the driver. Postscript is a double-edged sword with native PS-type applications such as Acrobat Reader. This might not be a requirement in your environment, but with languages like PCL, there are only a few commercial products that would allow for similar post conversion. Tools such as Adobe Acrobat, Ghostscript, GSView and many others can view and convert these files to PDF or other graphical formats. It’s also much easier to view, convert and otherwise post-process then most languages. This is useful for problem determination and isolation. As an example, if a job is printing from the wrong tray, you can capture the output and see what the application/driver has inserted for media source and type. It can be argued that Postscript output more accurately represents colours, is more efficient with graphics, and is more consistent from device to device.Ĭaptured output is human readable which makes it easier to interpret and debug. In most environments we would recommend using drivers in the following order (my order) of preference. To add to all of this, you probably have other applications where you have no control over the driver and language so you probably have a mixed environment already. So start with your preferred PDL and add others as you encounter applications or situations where another is required or works better, and don’t fear an environment that is not built around one language, in my experience this is almost impossible. Also, if you can limit the number of PDLs in your environment, it should make overall maintenance simpler. That being said, some PDLs are a little easier to work with post driver or when debugging. In the end, why do you really care what PDL you use? As long as when you press print your document comes out of the printer properly formatted who really cares how it go there or in what language? This then seems to spark all sorts of controversy which it shouldn’t. It's typically a very open ended question “should you use Postscript or PCL”. I'm often asked for my opinion on PDLs (Page Description Languages).
