Re: Post script and Non Post Script Printers |

This is a wide-open question.
Postscript drivers will write Postscript code to the PRN file or
device. A PCL driver will write PCL. Other drivers write whatever
sort of data/information is required for that particular printer.
I'm not familiar with PCL or other Page Description Languages, so I
won't try to discuss them further. I have a small understanding of the
Postscript language. It is a programming language (with loops,
variables, execution control statements, etc.). It also has some
built-in operators that work well for making marks on a page. Of
course, this is by design, and is a reason that Postscript is commonly
used as a printer language. A Postscript image can be device
independent, and thus can be printed on a variety of printers without
changing the program.
When printing to a Postscript printer, an acutal program is sent to
the printer. This program is executed, and the result is (usually)
that marks are made on a page and the page is printed.
If you want to learn more about the postscript language, look at
Adobe's site (www.adobe.com), look at comp.lang.postscript, or (if
you're feeling bold), get a copy of ghostscript for your computer, and
fiddle with it. It will run on most modern computers, and will let you
experience Postscript firsthand.

Can someone send me links/info on the basic difference between
Postscript and Non Postscript printers?
I am interested in learning what their drivers write to the PRN files
and if they do write any Printer/machine/date and time specific
metadata.
Any information will be of great help.
Thank you very much. |
