3.4. GUI Printing Tools
Most spooling systems alone offer only a rather basic command-line
interface. Rather than use lpr directly, you
may wish to obtain and use a front-end interface. These generally
let you fiddle with various printing options (the printer, paper
types, collation, n-up, etc) in an easy-to-use graphical way.
Some may have other features, as well.
KDEPrint allows users access to printing subsystems (CUPS, LPD, RLPR, LPRng etc.) through a KDE graphical user interface. With KDEPrint, you can easily print, administer jobs and printers and the printing daemon. KDEPrint is a replacement for the old QtCUPS and KUPS. It is easy to use for both developers and users. KDEPrint is already a part of KDE since 2.2.0 and has several nice features.
kprinter is the print dialog of KDEPrint which allows you to select the destination printer and change printer options. Among the destination printers, there are a few virtual printers allowing you to print to email, fax or pdf.
You can use KDEPrint's kprinter in any application that lets you configure your print command. Examples of these are Mozilla and OpenOffice.
Figure 2. Using kprinter with Mozilla
KDEPrint also features a Print Preview. that you can select from the Print Dialog. This is accomplished by passing the print file through the filters which make it suitable for displaying on screen using KGhostView or an external application like gv.
The KDEPrint Job Viewer KJobViewer allows you to view, move and cancel print jobs.
You can find more information about KDEPrint at https://printing.kde.org/.
Another good choice for CUPS is the program
(see Figure 4). XPP is built from the
FLTK library and is therefore desktop agnostic.
To print with XPP, simply run the xpp program, and specify a file
(or nothing, if you're using xpp in place of lpr to print from
stdin). Then select a printer from the list of configured
printers, and select any options you'd like to apply from the
various tabbed panels. See Figure 5
for an example options panel highlighting the standard CUPS
When used with Foomatic driver interface system, XPP will
also let you control numeric parameters not normally supported by
CUPS. This typically includes such things as extended color
tuning, cartridge alignment, and so forth. See Figure 6 for an example of this.
You can save your selected printer and all the options with the
`Save Settings' button.

by Thomas Hubbell, uses code from CUPS to filter Postscript jobs
and offer easy user control over job options. Some options (like
n-way printing, page selection, etc) are implemented directly by
GPR, while most others are implemented by the printer or by the
spooler's filter system.
GPR works with LPD or LPRng; or can be compiled specifically for
use with GNUlpr. When compiled normally, it
uses VA's libppd directly to produce printer-specific
PostScript which it will then submit to the lpr command. When
compiled for GNUlpr, it will submit your unmodified Postscript job
to the lpr command, along with the set of job options
you specify. This is arguably the better route, since it allows
the Postscript to be redirected to a different printer by the
spooler when appropriate; unfortunately it requires GNUlpr, which is not in wide circulation (although it is of
course trivial to install).
To use GPR, first select a printer (by LPD queue name) and check
that GPR has loaded the proper PPD file. If it hasn't, you'll
need to specify the PPD filename, and specify your printer's
options in the Printer Configuration dialog (you get this dialog
by pressing the Printer Configuration button; it contains
assorted printer setup options defined by the PPD).
Once you've configured your printer in GPR, you can print jobs by
specifying the filename and selecting the proper options from the
`Common' and `Advanced' tabbed panels. The `Common' options are
implemented directly by GPR for all printers, while the
`Advanced' options are defined by the PPD file for your printer.
You can see these option panels in Figure 8 and Figure 9.
