  11 Introduction
  12
  13 The Common UNIX Printing SystemTM, or CUPSTM, is provided under the GNU
  14 General Public License, Version 2. A copy of this license follows this
  15 introduction.
  16
  17 For those not familiar with the GNU General Public License, the license
  18 basically allows you to:
  19
  20    * Use the CUPS software at no charge.
  21    * Distribute verbatim copies of the software in source or binary form.
  22    * Sell verbatim copies of the software for a media fee, or sell support
  23      for the software.
  24    * Distribute or sell printer drivers and filters that use the CUPS API so
  25      long as source code is made available.
  26
  27 What this license does not allow you to do is make changes or add features
  28 to CUPS and then sell a binary-only distribution. You have to provide source
  29 for any new drivers, changes, or additions to the software.
  30
  31 Also, since we have trademarked the Common UNIX Printing System, CUPS, and
  32 CUPS logo, you may not release a derivative product using those names
  33 without permission from Easy Software Products.
  34
  35 Binary Distribution Rights
  36
  37 Easy Software Products also sells the CUPS source code under a binary-only
  38 license for vendors that are unable to release source code for their drivers
  39 or additions and modifications to CUPS under the GPL. For pricing
  40 information please contact us at the address shown above.
  41
  42 The Common UNIX Printing System utilizes GNU GhostScript 4.03 to convert
  43 PostScript files into a stream of raster images. For binary-only licensing
  44 of this software, please contact:

  75 Everyone is permitted to copy and distribute verbatim copies of this license
  76                  document, but changing it is not allowed.
  77
  78 Preamble
  79
  80 The licenses for most software are designed to take away your freedom to
  81 share and change it. By contrast, the GNU General Public License is intended
  82 to guarantee your freedom to share and change free software--to make sure
  83 the software is free for all its users. This General Public License applies
  84 to most of the Free Software Foundation's software and to any other program
  85 whose authors commit to using it. (Some other Free Software Foundation
  86 software is covered by the GNU Library General Public License instead.) You
  87 can apply it to your programs, too.
  88
  89 When we speak of free software, we are referring to freedom, not price. Our
  90 General Public Licenses are designed to make sure that you have the freedom
  91 to distribute copies of free software (and charge for this service if you
  92 wish), that you receive source code or can get it if you want it, that you
  93 can change the software or use pieces of it in new free programs; and that
  94 you know you can do these things.
  95
  96 To protect your rights, we need to make restrictions that forbid anyone to
  97 deny you these rights or to ask you to surrender the rights. These
  98 restrictions translate to certain responsibilities for you if you distribute
  99 copies of the software, or if you modify it.
 100
 101 For example, if you distribute copies of such a program, whether gratis or
 102 for a fee, you must give the recipients all the rights that you have. You
 103 must make sure that they, too, receive or can get the source code. And you
 104 must show them these terms so they know their rights.
 105
 106 We protect your rights with two steps: (1) copyright the software, and (2)
 107 offer you this license which gives you legal permission to copy, distribute
 108 and/or modify the software.
 109
 110 Also, for each author's protection and ours, we want to make certain that
 111 everyone understands that there is no warranty for this free software. If
 112 the software is modified by someone else and passed on, we want its
 113 recipients to know that what they have is not the original, so that any
 114 problems introduced by others will not reflect on the original authors'
 115 reputations.
 116
 117 Finally, any free program is threatened constantly by software patents. We
 118 wish to avoid the danger that redistributors of a free program will
 119 individually obtain patent licenses, in effect making the program
 120 proprietary. To prevent this, we have made it clear that any patent must be
 121 licensed for everyone's free use or not licensed at all.
 122
 123 The precise terms and conditions for copying, distribution and modification
 124 follow.
 125
 126 GNU GENERAL PUBLIC LICENSE
 127 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 128
 129   1. This License applies to any program or other work which contains a
 130      notice placed by the copyright holder saying it may be distributed
 131      under the terms of this General Public License. The "Program", below,
 132      refers to any such program or work, and a "work based on the Program"
 133      means either the Program or any derivative work under copyright law:
 134      that is to say, a work containing the Program or a portion of it,
 135      either verbatim or with modifications and/or translated into another
 136      language. (Hereinafter, translation is included without limitation in
 137      the term "modification".) Each licensee is addressed as "you".
 138
 139      Activities other than copying, distribution and modification are not
 140      covered by this License; they are outside its scope. The act of running
 141      the Program is not restricted, and the output from the Program is
 142      covered only if its contents constitute a work based on the Program
 143      (independent of having been made by running the Program). Whether that
 144      is true depends on what the Program does.
 145   2. You may copy and distribute verbatim copies of the Program's source
 146      code as you receive it, in any medium, provided that you conspicuously
 147      and appropriately publish on each copy an appropriate copyright notice
 148      and disclaimer of warranty; keep intact all the notices that refer to
 149      this License and to the absence of any warranty; and give any other
 150      recipients of the Program a copy of this License along with the
 151      Program.
 152
 153      You may charge a fee for the physical act of transferring a copy, and
 154      you may at your option offer warranty protection in exchange for a fee.
 155   3. You may modify your copy or copies of the Program or any portion of it,
 156      thus forming a work based on the Program, and copy and distribute such
 157      modifications or work under the terms of Section 1 above, provided that
 158      you also meet all of these conditions:
 159        a. You must cause the modified files to carry prominent notices
 160           stating that you changed the files and the date of any change.
 161        b. You must cause any work that you distribute or publish, that in
 162           whole or in part contains or is derived from the Program or any
 163           part thereof, to be licensed as a whole at no charge to all third
 164           parties under the terms of this License.
 165        c. if the modified program normally reads commands interactively when
 166           run, you must cause it, when started running for such interactive
 167           use in the most ordinary way, to print or display an announcement
 168           including an appropriate copyright notice and a notice that there
 169           is no warranty (or else, saying that you provide a warranty) and
 170           that users may redistribute the program under these conditions,
 171           and telling the user how to view a copy of this License.
 172           (Exception: if the Program itself is interactive but does not
 173           normally print such an announcement, your work based on the
 174           Program is not required to print an announcement.)
 175
 176      These requirements apply to the modified work as a whole. If
 177      identifiable sections of that work are not derived from the Program,
 178      and can be reasonably considered independent and separate works in
 179      themselves, then this License, and its terms, do not apply to those
 180      sections when you distribute them as separate works. But when you
 181      distribute the same sections as part of a whole which is a work based
 182      on the Program, the distribution of the whole must be on the terms of
 183      this License, whose permissions for other licensees extend to the
 184      entire whole, and thus to each and every part regardless of who wrote
 185      it.
 186
 187      Thus, it is not the intent of this section to claim rights or contest
 188      your rights to work written entirely by you; rather, the intent is to
 189      exercise the right to control the distribution of derivative or
 190      collective works based on the Program.
 191
 192      In addition, mere aggregation of another work not based on the Program
 193      with the Program (or with a work based on the Program) on a volume of a
 194      storage or distribution medium does not bring the other work under the
 195      scope of this License.
 196   4. You may copy and distribute the Program (or a work based on it, under
 197      Section 2) in object code or executable form under the terms of
 198      Sections 1 and 2 above provided that you also do one of the following:
 199        a. Accompany it with the complete corresponding machine-readable
 200           source code, which must be distributed under the terms of Sections
 201           1 and 2 above on a medium customarily used for software
 202           interchange; or,
 203        b. Accompany it with a written offer, valid for at least three years,
 204           to give any third party, for a charge no more than your cost of
 205           physically performing source distribution, a complete
 206           machine-readable copy of the corresponding source code, to be
 207           distributed under the terms of Sections 1 and 2 above on a medium
 208           customarily used for software interchange; or,
 209        c. Accompany it with the information you received as to the offer to
 210           distribute corresponding source code. (This alternative is allowed
 211           only for noncommercial distribution and only if you received the
 212           program in object code or executable form with such an offer, in
 213           accord with Subsection b above.)
 214
 215      The source code for a work means the preferred form of the work for
 216      making modifications to it. For an executable work, complete source
 217      code means all the source code for all modules it contains, plus any
 218      associated interface definition files, plus the scripts used to control
 219      compilation and installation of the executable. However, as a special
 220      exception, the source code distributed need not include anything that
 221      is normally distributed (in either source or binary form) with the
 222      major components (compiler, kernel, and so on) of the operating system
 223      on which the executable runs, unless that component itself accompanies
 224      the executable.
 225
 226      If distribution of executable or object code is made by offering access
 227      to copy from a designated place, then offering equivalent access to
 228      copy the source code from the same place counts as distribution of the
 229      source code, even though third parties are not compelled to copy the
 230      source along with the object code.
 231   5. You may not copy, modify, sublicense, or distribute the Program except
 232      as expressly provided under this License. Any attempt otherwise to
 233      copy, modify, sublicense or distribute the Program is void, and will
 234      automatically terminate your rights under this License. However,
 235      parties who have received copies, or rights, from you under this
 236      License will not have their licenses terminated so long as such parties
 237      remain in full compliance.
 238   6. You are not required to accept this License, since you have not signed
 239      it. However, nothing else grants you permission to modify or distribute
 240      the Program or its derivative works. These actions are prohibited by
 241      law if you do not accept this License. Therefore, by modifying or
 242      distributing the Program (or any work based on the Program), you
 243      indicate your acceptance of this License to do so, and all its terms
 244      and conditions for copying, distributing or modifying the Program or
 245      works based on it.
 246   7. Each time you redistribute the Program (or any work based on the
 247      Program), the recipient automatically receives a license from the
 248      original licensor to copy, distribute or modify the Program subject to
 249      these terms and conditions. You may not impose any further restrictions
 250      on the recipients' exercise of the rights granted herein. You are not
 251      responsible for enforcing compliance by third parties to this License.
 252   8. If, as a consequence of a court judgment or allegation of patent
 253      infringement or for any other reason (not limited to patent issues),
 254      conditions are imposed on you (whether by court order, agreement or
 255      otherwise) that contradict the conditions of this License, they do not
 256      excuse you from the conditions of this License. If you cannot
 257      distribute so as to satisfy simultaneously your obligations under this
 258      License and any other pertinent obligations, then as a consequence you
 259      may not distribute the Program at all. For example, if a patent license
 260      would not permit royalty-free redistribution of the Program by all
 261      those who receive copies directly or indirectly through you, then the
 262      only way you could satisfy both it and this License would be to refrain
 263      entirely from distribution of the Program.
 264
 265      If any portion of this section is held invalid or unenforceable under
 266      any particular circumstance, the balance of the section is intended to
 267      apply and the section as a whole is intended to apply in other
 268      circumstances.
 269
 270      It is not the purpose of this section to induce you to infringe any
 271      patents or other property right claims or to contest validity of any
 272      such claims; this section has the sole purpose of protecting the
 273      integrity of the free software distribution system, which is
 274      implemented by public license practices. Many people have made generous
 275      contributions to the wide range of software distributed through that
 276      system in reliance on consistent application of that system; it is up
 277      to the author/donor to decide if he or she is willing to distribute
 278      software through any other system and a licensee cannot impose that
 279      choice.
 280
 281      This section is intended to make thoroughly clear what is believed to
 282      be a consequence of the rest of this License.
 283   9. If the distribution and/or use of the Program is restricted in certain
 284      countries either by patents or by copyrighted interfaces, the original
 285      copyright holder who places the Program under this License may add an
 286      explicit geographical distribution limitation excluding those
 287      countries, so that distribution is permitted only in or among countries
 288      not thus excluded. In such case, this License incorporates the
 289      limitation as if written in the body of this License.
 290  10. The Free Software Foundation may publish revised and/or new versions of
 291      the General Public License from time to time. Such new versions will be
 292      similar in spirit to the present version, but may differ in detail to
 293      address new problems or concerns.
 294
 295      Each version is given a distinguishing version number. If the Program
 296      specifies a version number of this License which applies to it and "any
 297      later version", you have the option of following the terms and
 298      conditions either of that version or of any later version published by
 299      the Free Software Foundation. If the Program does not specify a version
 300      number of this License, you may choose any version ever published by
 301      the Free Software Foundation.
 302  11. If you wish to incorporate parts of the Program into other free
 303      programs whose distribution conditions are different, write to the
 304      author to ask for permission. For software which is copyrighted by the
 305      Free Software Foundation, write to the Free Software Foundation; we
 306      sometimes make exceptions for this. Our decision will be guided by the
 307      two goals of preserving the free status of all derivatives of our free
 308      software and of promoting the sharing and reuse of software generally.
 309
 310 NO WARRANTY
 311
 312  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 313      FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
 314      OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 315      PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
 316      EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
 317      WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
 318      ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH
 319      YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
 320      NECESSARY SERVICING, REPAIR OR CORRECTION.
 321  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 322      WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 323      REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
 324      DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
 325      DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
 326      (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
 327      INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
 328      THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR
 329      OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
 330
 331 END OF TERMS AND CONDITIONS
