UNIX Printing Software Administration and Installation Guide 6-876Running the SoftwareIn this chapter, you will learn about three separate commands that will run UNIXPrinting Software. Included in this chapter are descriptions for xlpsprint, lpspr andsdriver.About xlpsprint and lpsprBoth the xlpsprint command and the lpspr command give you the ability tomanipulate different printer models within a UNIX environment. The differencebetween the two commands is in the way you enter information into the system. Whenyou enter xlpsprint at the command line, a Graphical User Interface (GUI) willappear. From the GUI you can select a printer, and format its output. When you enterlpspr at the command line, you have the exact same functionality as xlpsprint,except that the tasks must be accomplished through a command line interface.Both commands require data files known as Postscript Printer Description (ppd) files.Each printer model will have its own PPD file.Your installation kit also provides configuration files, including a Model to ppd file(mdl2ppd). Other files in your installation kit include: a Printer-to-Model Map File(printer2mdl) and a lpsprodb file. Both files are system specific and are locatedunder the /etc directory.The mdl2ppd file, as well as a set of postscript program files used by xlpsprint andlpspr can be found in the location pointed to by LPSROOT/ppd. You select thelocation of LPSROOT during the installation process. Typically, the mdl2ppd file andthe postscript program files are compatible for all UNIX system types.A description of the above system files are as follows:
