When the user enters the ID and password (step 13), the user PC transfers it to the print server, and the print server requests the user authentication information and balance information from the management server (step 21).

When the management server extracts the user authentication information and the balance information from the database and sends it to the print server (step 31), the printer server compares the user ID and password to authenticate the user (step 22).

If authentication fails because the user ID or password do not match, the user PC causes the authentication failure message to be displayed (step 14), and the process returns to the step of displaying the user ID and password input window.

If the user authentication is successful, the print server sends the user's balance information to the user's PC (step 23), the user's PC checks the number and format of the document to be printed, calculates the printing cost, and the user's balance is the printing cost. Determine if more (step 15).

If the balance of the user is less than the printing cost, the balance shortage message is displayed (step 16), and the process returns to the step of displaying the user ID and password input window or ends.

If the user's balance is greater than the printing cost, the print content data is sent to the print server (step 17), and the print server checks the status and job load of the printer or printer specified by the user and prints to the less loaded printer. The content data is output and printed (step 24).

Once the print job is complete, the print server prints information about the cost of printing, including the cost of printing and the balance of the user after subtracting it, the user who printed it, the name of the printed document, the number and type of pages (printed form, color, etc.), and the printer that printed it. The print information such as ID is sent to the management server (step 25), and the management server classifies the user's balance information and print information and stores it in the database (step 32).

At the same time, the print server transmits the print result and the printing cost information to the user PC (step 26), and the user PC displays this for the user to confirm (step 18). The printing result and the printing cost information displayed at this time include the location of the printed printer, the printing cost, the balance information of the user whose printing cost is subtracted, and the like.
