README - CUPS v2.1b1 - 2015-02-03

Looking for compile instructions? Read the file "INSTALL.txt" instead...

INTRODUCTION

CUPS is a standards-based, open source printing system developed by Apple
Inc. for OS® X and other UNIX®-like operating systems.  CUPS uses the
Internet Printing Protocol ("IPP") and provides System V and Berkeley
command-line interfaces, a web interface, and a C API to manage printers and
print jobs.  It supports printing to both local (parallel, serial, USB) and
networked printers, and printers can be shared from one computer to another,
even over the Internet!

Internally, CUPS uses PostScript Printer Description ("PPD") files to
describe printer capabilities and features and a wide variety of generic
and device-specific programs to convert and print many types of files.
Sample drivers are included with CUPS to support many Dymo, EPSON, HP,
Intellitech, OKIDATA, and Zebra printers.  Many more drivers are available
online and (in some cases) on the driver CD-ROM that came with your printer.

CUPS is licensed under the GNU General Public License and GNU Library
General Public License versions 2.  See the file "LICENSE.txt" for more
information.

READING THE DOCUMENTATION

Once you have installed the software you can access the documentation (and
a bunch of other stuff) online at:

http://localhost:631/

If you're having trouble getting that far, the documentation is located
under the "doc/help" directory.

Please read the documentation before asking questions.

GETTING SUPPORT AND OTHER RESOURCES

If you have problems, READ THE DOCUMENTATION FIRST!  We also provide two
mailing lists which are available at:

http://www.cups.org/lists.php

See the CUPS web site at "http://www.cups.org/" for other resources.

SETTING UP PRINTER QUEUES USING YOUR WEB BROWSER

CUPS includes a web-based administration tool that allows you to manage
printers, classes, and jobs on your server.  Open the following URL in your
browser to access the printer administration tools:

http://localhost:631/admin/

DO NOT use the hostname for your machine - it will not work with the default
CUPS configuration.  To enable administration access on other addresses,
check the "Allow Remote Administration" box and click on the "Change
Settings" button.

You will be asked for the administration password (root or any other user in
the sys/system/root/admin/lpadmin group on your system) when performing any
administrative function.

SETTING UP PRINTER QUEUES FROM THE COMMAND-LINE

CUPS works best with PPD (PostScript Printer Description) files.  In a pinch
you can also use System V style printer interface scripts.

CUPS includes several sample PPD files you can use:

Driver                         PPD Name
-----------------------------  ------------------------------
Dymo Label Printers            drv:///sample.drv/dymo.ppd
Intellitech Intellibar         drv:///sample.drv/intelbar.ppd
EPSON 9-pin Series             drv:///sample.drv/epson9.ppd
EPSON 24-pin Series            drv:///sample.drv/epson24.ppd
Generic PCL Laser Printer      drv:///sample.drv/generpcl.ppd
Generic PostScript Printer     drv:///sample.drv/generic.ppd
HP DeskJet Series              drv:///sample.drv/deskjet.ppd
HP LaserJet Series             drv:///sample.drv/laserjet.ppd
OKIDATA 9-Pin Series           drv:///sample.drv/okidata9.ppd
OKIDATA 24-Pin Series          drv:///sample.drv/okidat24.ppd
Zebra CPCL Label Printer       drv:///sample.drv/zebracpl.ppd
Zebra EPL1 Label Printer       drv:///sample.drv/zebraep1.ppd
Zebra EPL2 Label Printer       drv:///sample.drv/zebraep2.ppd
Zebra ZPL Label Printer        drv:///sample.drv/zebra.ppd

Run the "lpinfo -m" command to list the available drivers:

    lpinfo -m

Run the "lpinfo -v" command to list the available printers:

    lpinfo -v

Then use the correct URI to add the printer using the "lpadmin" command:

    lpadmin -p printername -E -v device-uri -m ppd-name

Network printers typically use "socket" or "lpd" URIs:

    lpadmin -p printername -E -v socket://11.22.33.44 -m ppd-name
    lpadmin -p printername -E -v lpd://11.22.33.44/ -m ppd-name

The sample drivers provide basic printing capabilities, but generally do not
exercise the full potential of the printers or CUPS.

PRINTING FILES

CUPS provides both the System V "lp" and Berkeley "lpr" commands for
printing:

lp filename
lpr filename

Both the "lp" and "lpr" commands support printing options for the driver:

lp -o media=A4 -o resolution=600dpi filename
lpr -o media=A4 -o resolution=600dpi filename

CUPS recognizes many types of images files as well as PDF, PostScript,
and text files, so you can print those files directly rather than through
an application.

If you have an application that generates output specifically for your
printer then you need to use the "-oraw" or "-l" options:

lp -o raw filename
lpr -l filename

This will prevent the filters from misinterpreting your print file.
