Post script printing

We are using a new aplication program which is using prining with "post script".
Can anybody tell me what exactly "post script" printing.What is the difference with normal printing.Also how to use it in hp-ux.

Postscript is a text markup language. It was developed by Adobe. http://www.adobe.com/products/postscript/main.html

It's used mainly with printing to get output that has graphics, multiple font and sizes.

Another print markup language is HP's PCL. Some info on that at http://cbbrowne.com/info/pcl.html

Without those you're limited to plain old ASCII text.

Normally it's just a matter of configuring the correct driver for the printer. To take advanatage of postscript. There are some tool such as Ghostscript that can be used to interpret postscript files. Hope that helps some.

Postscript is a printer language. The vast majority of printers understand plain ASCII text, and HP printers add enhancements to ASCII in the form of escape sequences to handle graphics and fonts, etc. That is called PCL (Printer Control Language). HP-UX does not translate PCL or Postscript. If an application produces Postscript, you must send it to a Postscript printer. The printer scripts in HP-UX cannot translate the Postscript code into something else. The freeware program Ghosscript can be used to translate Postscript into PCL but this can sometimes be a problem if the PCL output from Ghostscript is to advanced for the printer you have.

By far the easiest way is to use a printer that has Postscript built-in. Sme models of HP printers have Postscript built-in, others have Postscript as an optional add-on, and some do not have any Postscript capability. Note also there are levels of Postscript. Level is only black&white, higher levels have color capability, but the printer must understand the higher Postscript level even if the image is black&white.
