Linux LPR Properties Dialog
Properties can be changed for each printer on the system, including printers from other manufacturers.
However advanced options are only available for Linux printers.
For options to be kept between LLPR sessions, click the Save button at the bottom of the dialog.
General
This tab allows you to change the used paper size for printing, the orientation of the documents,
enable duplex features, add start and end banners, and change the number of pages per sheet.
- Paper Size:
Choose the appropriate size of the paper. Different printers may have different choices available.
- Orientation:
You can choose to print the document in portrait mode (default), landscape, and optionally reverse them (make the pages up-side down). Be careful when using these options with PostScript documents, as they will rotate the page. Most applications will generate landscape data when you select this option from the application printing dialog. In that case, to achieve the correct results, you should let that setting in LLPR to the default portrait orientation.
- Duplex Printing:
If the printer supports Duplex Printing (printing on both sides of the pages), it can be enabled here. The Long Edge is suitable for landscape pages, while the Short Edge setting is suitable for portrait pages.
- Banners:
Optional banner pages can be specified. These pages will be printer before and after the job, for instance to indicate the classification of the document. Available banner types include "Classified", "Confidential", "Secret", "Top Secret", "Standard" and "Unclassified".
Warning: Some printing systems (such as BSD LPD) won't allow some informations, such as the job ID number, to be printed in the banners.
- Pages per sheet:
This affects the N-up setting, and allows to print several pages on the same sheet. This enables you to print 2 or 4 pages of the document on a single page.
Margins
- Page Margins: You can override the default setting for the page margins here. The graphic on the right shows the current settings. You can redefine the margins in three different units : points, inches ("in"), and centimeters ("cm"). Please note that these margins don't apply when printing regular PostScript data.
Image
The image tab allows you to set options that will be used when printing image files through LLPR directly,
i.e. when a non-Postscript document is passed on the command line. Supported image formats include JPEG,
GIF, PNG, BMP, TIFF, PhotoCD, RGB, PPM, XPM, XBM, and Sun Raster.
- Color Settings
You can adjust the level of brightness, hue (tint) and saturation (color) used to render the images on the printer. Please note that when using a monochrome printer, the hue and saturation parameters will have no visible effect.
When moving the sliders, changes are showed in real time on the image on the right, giving you an idea of what the settings will look like on paper. Unlike other settings, the Brightness setting may also apply to other non-image jobs (regular PostScript documents).
- Gamma:
The gamma correction setting affects all Postscript jobs, not only the images that are passed to LLPR.
- Image Size:
You can define the size of the image on the page, if it needs to be scaled. The percentage of the page can be set over 100%, which would make the image span across several pages.
The resolution (in Points Per Inches) defines the density of pixels on the page. The higher this
value is, the less space the image will take on paper, and vice versa.
- Image Position:
Choose the position of the image, which can be in any of the corners or sides of the page, or in the center (by default).

Text
- Text Format: The density of the text can be selected by choosing the number of characters per inch, and lines per inch. Optionally, you can span the text among several columns on each page.
- Syntax Coloring: This turns on the syntax coloring for source code, as well as "pretty printing", which means that each page will also include the page number and the date in its header.
HP-GL/2
LLPR is able to print documents in the HP-GL/2 format, which is used by some plotters and also as an
interchange format for some CAD software.
- Use only black pen: This will force all pens to plot in black.
- Fit plot to page: The plot will be scaled to fit the page.
- Pen width: This specifies the default pen width in micrometers (1/1000th of a millimeter). The default value is 1000, which is 1 millimeter. A value of 0 will produce lines of exactly 1 pixel in width.
Advanced
This tab allows you to override the default settings for the printer.
Since some of these settings may sometimes be in conflict with each other, you won't be able to click on OK or Save until all conflicts have been resolved.
