10. APPENDIX - DETAILED SCENARIOS

   The following are more detailed scenarios illustrating how the
   Internet Printing Protocol is expected to be used as a part of a
   complete Internet Printing system.  Some parts of the scenarios
   include concepts, functions and information that may be outside of
   the scope of version 1.0 of IPP (e.g. cost per page, payments means
   available, etc.)  The information contained herein is meant to be
   generic.  There may not be an exact wording or terminology match
   between these scenarios and the implementation documents.

10.1. PRINTER DISCOVERY WITHIN AN ENTERPRISE

   A user wants to find a color Postscript printer in his/her enterprise
   which will print transparencies. The client, directory service, and
   printer are all behind the same corporate firewall. Because color
   foils are expensive, printers of this type are access controlled and
   require an account to be established so that printing can be billed
   back to the using department. Note the request to find a printer
   usable by Dept.  J15. Drivers for all supported printers are
   available from the server they are associated with. A help desk is
   provided for end user support.  The printer is unattended.

   Client                                  Directory Service

      +---------------------------------------------------------- >
        Find a printer with these characteristics

10.2. PRINTER DISCOVERY ACROSS ENTERPRISES

   A user in Company A wants to find a public printer in a business
   partner's enterprise (Company B) on which to print a purchase order.
   The client is behind one corporate firewall and the directory service
   and the printer are behind a different corporate firewall. Drivers
   for all supported printers are available from the server they are
   associated with. A web page is provided for end user support for
   public printers.

   Client                        Company B Directory Service

      +---------------------------------------------------------- >

10.3. PRINTER DISCOVERY ON THE INTERNET -LOGICAL OPERATIONS

   A student wants to print a paper on a printer at his neighborhood
   Ink-o's print shop. The report was written using Microsoft Word. The
   student is interested in the cost of printing since his budget is
   limited. Note the use of logical operators to find this information.

   An executive in her hotel room is finishing an important presentation
   on her laptop computer. She connects to a local print shop through
   the web to get a copy of her charts printed for tomorrow's
   presentation.  She must find a print shop that is convenient to her
   hotel and can print color transparencies. She wants to be sure that
   the printer can be authenticated and can accept encrypted data.

10.5. DRIVER DOWNLOAD

   An end user in an enterprise wants to print a lengthy report on a
   newly installed high speed PostScript printer. Since she will likely
   use this printer often, she would like to download a driver and
   install it on her workstation. She is running Windows 95.  Note:
   Driver download is not a V1.0 design goal.

10.6. SUBMITTING A PRINT JOB AS A FILE

   An end-user wants to submit a print job. The print file already
   exists on his workstation. The client and printer are behind the same
   corporate firewall. The printer is available to anyone behind the
   firewall and no authorization or authentication is required. The data
   is pushed to the printer. The printer is capable of spooling the
   output. No errors occur.

   Client                                        IPP Printer

      +---------------------------------------------------------- >
        Here is a print job
        - job name = MyJob

        - print on iso-a4-white paper
        - print on both sides of the paper
        - return status of the printer in response
        - document is in Postscript format
        - here is the document to print

      < ----------------------------------------------------------+
        Print job accepted and spooled

        - submission time = 02/12/97, 15:35
        - printer state = printing

10.7. SUBMITTING A PRINT JOB WITH TWO DOCUMENTS

   An end-user wants to submit a print job. The print file already
   exists on his workstation. The client and printer are behind the same
   corporate firewall. The printer is available to anyone behind the
   firewall and no authorization or authentication is required. The data
   is pushed to the printer. The job consists of two separate documents.
   The printer is capable of spooling the output. No errors occur.
