Description Ghostscript is the name of a set of software that provides an interpreter for the PostScriptTM language and the Adobe Portable Document Format (PDF -- sometimes confused with Acrobat, Adobe's PDF browser and editor product).
It can be used to store nice plots from the CitectSCADA TrnPrint and TrnPlot functions produced by your printer in a file.
Input modules (utilities) for reading a variety of raster formats, including CMYK, GIF, JFIF (JPEG), MIFF, PBM/PGM/PPM, and PCX
Output modules (drivers) for a wide variety of window systems (including X Windows and Microsoft Windows), raster file formats, and printers, as well as a PDF output module that implements functions similar to Adobe's AcrobatTM DistillerTM product.
The Ghostscript library, a set of procedures to implement the graphics and filtering capabilities that are primitive operations in the PostScript language and in PDF.
In simple terms, this means that Ghostscript can read a PostScript or PDF file and display the results on the screen or convert them into a form you can print on a non-PostScript printer. Especially together with several popular previewers, with Ghostscript you can view or print an entire document or even isolated pages, even if your computer doesn't have Display PostScript and your printer doesn't handle PostScript itself.
