10.8. SUBMITTING A PRINT JOB AS A FILE, PRINTING FAILS

   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 not capable of spooling the
   output so it begins printing while still receiving the file. An error
   occurs and the printer cannot complete printing (in this case the
   user requires A4 paper and that paper size is not available on the
   printer.)

10.9. SUBMITTING A PRINT JOB WITH AUTHENTICATION, PRIVACY AND PAYMENT

   A traveling executive needs to print a set of transparencies for an
   important business meeting. The charts are in Lotus Freelance format
   on his notebook computer. He has located a SirZippy print shop near
   his hotel that will print color transparencies. Because the
   information on the charts is sensitive, he wants to be sure that his
   data is sent to the Printer in an encrypted format. He also wants to
   authenticate the Printer. The Printer also authenticates the user.
   Payment occurs across the Internet.

10.10. SUBMITTING A PRINT JOB WITH DECRYPTION ERROR

   A traveling executive needs to print a set of transparencies for an
   important business meeting. The charts are in Lotus Freelance format
   on his notebook computer. He has located a SirZippy print shop near
   his hotel that will print color transparencies. Because the

10.11. SUBMITTING A PRINT JOB WITH AUTHENTICATION

   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 but authentication and authorization is required.
   Authorization takes place using the authenticated end-user's name.
   The data is pushed to the printer. The printer is capable of spooling
   the output.

10.12. SUBMITTING A PRINT JOB GENERATED DYNAMICALLY

   An end-user wants to submit a print job. The print data is generated
   dynamically and is being transmitted by a printer driver on the
   client workstation as available. The client and printer are behind
   the same corporate firewall. The printer is available to anyone
   behind the firewall and no authentication and authorization is
   required. The data is pushed to the printer. The printer is capable
   of spooling the output.  No error occurs.

10.13. SUBMITTING A PRINT JOB WITH A PRINTER JAM - CANCELED

   An end-user wants to submit a print job. The print data is generated
   dynamically and is being transmitted by a printer driver on the
   client workstation as available. The client and printer are behind
   the same corporate firewall. The printer is available to anyone
   behind the firewall and no authentication and authorization is
   required. The data is pushed to the printer. The printer is not
   capable of spooling the output. The printer jams notifies the user
   and the user chooses to cancel the job.
