  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 under the GPL.
  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 distribution without source code. You have to
  29 provide source for any new drivers, changes, or additions to the software,
  30 and all code must be provided under the GPL.
  31
  32 Also, since we have trademarked the Common UNIX Printing System, CUPS, and
  33 CUPS logo, you may not release a derivative product using those names
  34 without permission from Easy Software Products.
  35
  36 Binary Distribution Rights
  37
  38 Easy Software Products also sells rights to the CUPS source code under a
  39 binary distribution license for vendors that are unable to release source
  40 code for their drivers or additions and modifications to CUPS under the GPL.
  41 For pricing information please contact us at the address shown above.

  43 The Common UNIX Printing System utilizes GNU GhostScript 4.03 to convert
  44 PostScript files into a stream of raster images. For binary distribution

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