Description

The printer selection method described in Patent Document 2 and the data processing apparatus described in Patent Document 3 are difficult to cope with a change in the quality of printed matter in a print job due to printer performance fluctuations. It is intended to select a printer for printing from among a plurality of printers connected to the network, but not to select the optimum printing conditions for each printer.

The printing condition change examination unit 26 includes a printing management information prediction unit 28 that predicts a change in printing management information under the changed printing conditions. Print management information prediction unit 28, when it is determined that Ru is expected to improve the evaluation of printed matter during printing by changing the printing conditions also predicts the change in the print management information in the print-condition after the change.

Numeral 600 in FIG. 11 is a relationship between the evaluation of the screen ruling and the particulate quality schematically shown, reference numeral 602 shows the relationship between the evaluation of the number of screen lines and moire image quality schematically. The number of screen lines is the number of lines per unit length, and the unit is inches per line. The screen line number is a quality evaluation index similar to the resolution mentioned as the quality print management information.

Equation (8), in equation (9), and equation (10), the variable q, c, in consideration of the fact that d is not all existent may become zero, the evaluation function F is a type using a natural logarithm However, the evaluation functions shown in Expression (8), Expression (9), and Expression (10) are merely examples, and various types of evaluation functions using q, c, and d as variables can be applied. .
