Print to a low end inkjet printer from an application

1. Example Use Model:

Dorothy has been editing and formatting her biology term paper for weeks.
She takes her laptop computer to class and constantly updates her term paper
with new information from the lectures and labs.   She uses her portable
scanner and graphics editor to illustrate the step-by-step processes in her
term paper as well as the final charts and graphs which will are all
integrated into her word processor.  She does not final edit the night
before.  Then she loads her 2000XYZ-Color inkjet printer with the special
paper required by the professor; she connects the USB cable from her printer
to her laptop and she’s ready to print.   She has already formatted the
print job but brings up the print preview window to double check as the
special paper is expensive.   Finally, she brings up the print dialog box
and makes her selections.  She selects collated copies, highest print
quality and background printing mode before hitting the print button (she
still has work on her chemistry assignment).  Thirty-eight minutes later she
removes the printed pages,  carefully inspects each page and staples each
copy into special cover sheets for the biology class.

3.5 Use Model 4:  Desktop Small-Office / Home-Office Printing

Print to mid-volume laser printer, office inkjet and impact printers

1. Example Use Model:

Keith’s small company produces about 5000 widgets a month for a large

the data base software and now request data sheets (in post-script) for each
widget.  Keith spent weeks designing/creating the template for the data
sheets, including color and graphics.  Navigating to the directory with this
month’s data sheets; he again sends post-script formatted data sheets to the
print system, requesting two copies of each data sheet on the office inkjet
printer.

workplaces

Example Use Model:

Till is working in an office with three other employees; namely, Claudia,
Mark and Glen that have individual computers.  In the same room there are
two printers; specifically, a low-volume color inkjet connected to Mark’s
computer and a low-volume black/white laser printer connected to Glen’s
computer for printing confidential material.   Till wants to print some
color documents to the color inkjet printer and print his black-and-white

asks all print servers for their basic printer capabilities. As an example
the following is returned for the color inkjet, laser print and the central
hallway printer;
      inkjet:Mark         6-ink photo color printer,  room of W, X, Y, and
Z;
laser:Glen          desktop bw laser printer, 10 p/min,  room of W, X, Y,

3.8 Use Model 7: Desktop File (Direct) Printing

Print to print service directly from file-manager/shell-script with going
through an application

1. Example Use Model:

Robert is the lead engineer on the power subsystem of the companies next
generation satellite.   He has spent the last 6 month working with
individual engineering and other departments on no less than 12 interrelated
specifications and design documents.  People have been delivering him
post-script versions of their document over the last several days.  Robert
recently bought a wide format color inkjet printer from the Acme print copy.
The printer has great output resolution and an extended color gammit but
does not print post script natively; so Robert download and installs the
latest version of GhostScript along with the print driver.  Robert types in
the print options, printer model and location of the print data for
GhostScript at the command line and wait for each document to printed.
Robert begins the task of checking and removing ambiguities between the
specifications.


Use Model 8: Pay for Print

Print using a job ticket from a print driver through a print spooler to a
mid-range (90 PPM) color laser printer.

Amy is a student at the university who has to do research on controlling
forest fires near densely populated areas. She decides to go the library at
the university so that she can access restricted archives of information
pertaining to her topic. The database contains research papers that have
information that is controversial, so some of the information has never been
made public.

Amy was given a PrintCard by the university at the beginning of the semester
that gives her $10 worth of print credit. The PrintCard has a magnetic strip
which is encoded with her student Id and the balance for her printing
account. Duplex black/white prints cost 10 cents per sheet and duplex color
prints cost $1 per sheet. The student must enter their student ID and a PIN
code to use the PrintCard.

Amy searches the restricted archives and finds a paper of interest, both for
use in her research and to her parents whose house was recently burned down
by a forest fire. The paper is formatted to print on legal size paper and
has front and back cover sheets.

Amy selects the Print menu item on the Netscape browser and the Print dialog
displays. Sher selects a printer called ColorLibraryPrinter. She selects
legal size paper, duplex, covers, left corner staple, and two copies (one
for her parents and one for herself). She clicks the OK button.  A dialog
displays asking her to swipe her PrintCard and to enter her student ID and
PIN number. She does as instructed and clicks OK.

A print application is called by the print driver to create a job ticket
that contains the information that Amy selected in the Print dialog. The
print application prepends the job ticket that it generated to the
postscript file that was generated by the print driver and returns the
result to the print driver. The print driver makes contact with Print
Services and sends the print job that contains the ticket prepended to the
postscipt file to the Print Service over the network. The Print Service
recognizes the print job as a ticketed job, strips off the job ticket and
consumes the job ticket. From the consumed job ticket, the Print Services
extracts the name of the printer that the print job is to be sent to and
maps the name to the IP address of the printer. The Print Service contacts
the printer called ColorLibraryPrinter using its IP address and sends the
print job that contains the job ticket prepended to the  postscript file to
ColorLibraryPrinter. ColorLibraryPrinter receives the print job, recognizes
that the print job as a ticketed job, strips off the job ticket, and
consumes the job ticket.

Amy wallks to the first floor of the library to the printer labeled
ColorLibraryPrinter. She swipes her PrintCard and enters her student ID and
PIN on the printer console when prompted. A summary of Amy's print job
appears on the printer console asking her if the options are correct. Amy
has decided to also print a copy of the paper for her brother Tim, so she
changes the number of copies to three and clicks OK. Amy's print job
completes printing. She picks up her print job from the printer's over-size
output bin and examines the output. A message on the printer console asks if
the print output looks okay. Amy clicks OK and her print account is debited.
Amy swipes her PrintCard again to update it with her new accont balance. Amy
leaves the library with the three copies of the research paper.
