Using Ghostscript in FoxWeb
The following instructions provide information on the use install and test Ghostscript in order to use it to generate PDF files from your FoxWeb scripts. Ghostscript is an interpreter for PostScript and PDF files, with the ability to convert these files to several other formats and to each other. It also provides a PostScript printer driver, which you can use to produce PDF files. Versions entitled GPL Ghostscript are distributed with the GNU General Public License, which allows free use, and free copying and redistribution under certain conditions (including, in some cases, commercial distribution). For details please check the Ghostscript web site, or this site. The creation of PDF files with FoxWeb and Ghostscript is a two step process: First you must direct your report output to a PostScript file and then you must use Ghostscript to convert this file to PDF format.

Printing with Qt
Qt provides extensive cross-platform support for printing. Using the printing systems on each platform, Qt applications can print to attached printers and across networks to remote printers. Qt's printing system also enables PostScript and PDF files to be generated, providing the foundation for basic report generation facilities.

There are, however, no 'default margins' in Ghostscript, it can and will print right to the edge of the media. Any margins must be set elsewhere.
...
Ghostscript won't impose margins, so any margins you see must be written into the PostScript program it receives, which means the application doing the layout is inserting the margins.

Standard Printing Options

The following options apply when printing all types of files.

Selecting the Media Size, Type, and Source

The -o media=xyz option sets the media size, type, and/or source:

Setting the Page Margins

Normally the page margins are set to the hard limits of the printer. Use the -o page-left=value, -o page-right=value, -o page-top=value, and -o page-bottom=value options to adjust the page margins:

lp -o page-left=value filename
lp -o page-right=value filename
lp -o page-top=value filename
lp -o page-bottom=value filename
lpr -o page-left=value -o page-right=value -o page-top=value -o page-bottom=value filename
The value argument is the margin in points; each point is 1/72 inch or 0.35mm.

Creating Saved Options

Saved options are supported in CUPS through printer instances. Printer instances are, as their name implies, copies of a printer that have certain options associated with them. Use the lpoptions command to create a printer instance:

lpoptions -p printer/instance -o name=value ...
