You can open the print dialog by choosing the menu command File->Print.
With Print Destination you can determine whether to invoke a print command or write the output to a file. The command for the commonly used BSD lpr printer spooling system for instance would be lpr -Pprinter. For CUPS it should be lp -dprinter.
With Paper Format you can specify the format of the paper used by the printer.
From Page and To Page determine the range of pages to be printed within the facsimile document.
Number of Copies determines how many times each page should be printed.
With Language Level 2 you can activate the level 2 extensions of the PostScript(R) language. It is recommended to keep this option turned on since it makes the output much smaller. If you have problems with your PostScript(R) interpreter retry it with this option turned off.
With Interpolate you can make the PostScript(R) interpreter interpolate the pixels for a smoother output. This may slow down the print process. This option is only available with the Language Level 2 option turned on.
