Costs page it is intended for setting of printed page cost, depending on a used format of a paper, cost of a toner or the ink necessary for a printing of one page and a mode of a printing (the duplex printing is used or the printing is conducted on one side of a sheet).

For setting of the cost parameters you need to know cost of a sheet of a paper for the chosen format and cost of a toner or the ink, spent for printing of one side of a page (for color and (or) a monochrome mode of printing).

Cost of one sheet of a paper is determined division of cost of the package into quantity of sheets in it. For example, for paper ( format А4)  which costs of 5 USD and containing 500 sheets this value will be 5/500 = 0.01 USD per sheet.

Cost of a toner on one page calculates proceeding from cost of a cartridge and its resource. For example, for printer Samsung ML-1250, a monochrome mode of a printing, cost of a cartridge 55 USD. The cartridge resource is 1500 pages. Then cost of a toner per one printed page is 55/1500 = 0.04 USD.

Similarly for a cartridge for the color printer. If your printer does not support a color printing you do not need to setup cost of a toner for a color mode and on the contrary if the printing is conducted only in colour you do not need to setup cost for a monochrome mode.

Cost of the printed page calculates depending of a paper format and a mode of printing (monochrome, color, a duplex):

1. Monochrome printing without duplex, page format A4:

 Page_Cost = Paper_Cost + Monochrome_Toner_Per_Page_Cost;

2. Monochrome printing with duplex, page format A4:

 Page_Cost = Paper_Cost +( Monochrome_Toner_Per_Page_Cost * 2);

3. Color printing without duplex, page format A4:

 Page_Cost = Paper_Cost + Color_Toner_Per_Page_Cost;

4. Color printing with duplex, page format A4:

 Page_Cost = Paper_Cost +( Color_Toner_Per_Page_Cost * 2);

Calculation of cost can be made by two ways:

Method 1. Cost of page is defined for each used format. In this case when a page is printed on a format which cost is set, calculation will be is made using the set parameters. If parameters for the given format are not defined, cost of page will be 0;
Method 2. Cost only for a base format is defined. In this case parameters of cost for one format are set and this format is defined as a base format. At calculation of a printed page cost the scale factor  is used. Scale factor  is a ratio of the areas of a printed page and base format page. Calculation is made by definition of a page cost for a base format and multiplied on the scale factor.

Enable Accounting Engine - enables or disables calculating costs for printed pages.

Use Base Format Only - Instructs the program to use the Method 2 for calculation of printing cost, if this switch it is on. When this switch is off,  the method 1 is used. More in detail about these methods you can read above.

Paper Sheet Cost - In this field you should to define the cost of one sheet of a paper for the chosen format.

Color Toner/Ink Cost per Sheet - In this field you should to define cost of a color toner (or ink), spent  for printing one sheet of a paper of the chosen format.

Monochrome Toner/Ink Cost per Sheet - In this field you should to define cost of a monochrome toner (or ink), spent  for printing one sheet of a paper of the chosen format.

Page Cost for Color - This field displays printing cost for one color page for the chosen format.

Page Cost for Monochrome - This field displays printing cost for one monochrome page for the chosen format.

Duplex Page Cost for Color - This field displays printing cost for one color page for the chosen format using duplex printing.

Duplex Page Cost for Monochrome - This field displays printing cost for one monochrome page for the chosen format using duplex printing.

Base Format - This switch defines the chosen format as a base format.

Remove Format - Using this button you can remove formats of a paper which you do not use for this printer.

Remove All Formats - Using this button you can remove all formats of a paper for this printer.

Reset All Formats - This option recreates the list of paper formats for this printer. ATTENTION: all printing cost settings for all formats for this printer will be lost!

Refresh All Formats - This option updates the list of paper formats for this printer. All printing cost settings for all formats for this printer will be kept. You should setup printing cost for added formats if such is.

Save Accounting Settings - This option saves printing cost settings for all formats for all printers.

At the bottom of the window there are three buttons: OK (closes a window with saving the modified data submitted in a window), Apply (not closing a window, saves the data, submitted in a window) and Close (closes a window, discards the data). If the user has started the console as the "observer" role, after closing the program all modification will lost. Change the settings of gathering of the information the user "Administrator" can only do.
