Abstract: A terminal device as a prohibited relationship detection device detects presence or absence of a prohibited relationship, when change of a setting value related to a job condition is received, based on a PJL (Printer Job Language) index table to classify a plurality of configuration items of which input of setting values is received on the terminal device into a plurality of resolve tables, a plurality of resolve PJL tables showing relationship between setting values of which input is received on the terminal device and the PJL values which indicate the setting values of which input is received on the terminal device in the PJL, and an inter resolve PJL table prohibition table which shows a combination of setting values having a prohibited relationship, of which input is received on the terminal device.

Abstract: An apparatus determines, when values of at least three items are mutually in a restriction relationship where applying the values concurrently are prohibited, avoidance processing for avoiding the restriction relationship. The apparatus includes a storage portion for storing degree of importance of each of at least three items; and a determination portion configured to set one item of at least three items at a trigger item, determine whether the restriction relationship is to be avoided by changing the value of a lower item to another value, the lower item being an item given the degree of importance lower than or equal to that of the trigger item, and determine, when the restriction relationship is determined to be avoided, processing of changing the value to that another value as the avoidance processing used when the value is to be set for the trigger item.

Abstract: An apparatus for assigning a print job is provided. The apparatus includes a detector configured to detect an ambient temperature of each of a plurality of areas, each of the areas including at least one printer and at least one air conditioning system; a selection portion configured to select a printer included in a suitable area of the areas, the suitable area being an area where the ambient temperature detected is lower than a predetermined temperature; and an issuing portion configured to give the print job to the printer selected.

Abstract: A printing system is provided with a terminal sending print data; a printer performing printing based on the print data; and a transfer device transferring the print data to the printer responding to a request from the printer. The terminal includes a transmission portion configured to, when communication with the transfer device is possible, send the print data to the transfer device, and configured to, when the communication is impossible, send the print data in association with a command for authentication print to the printer without via the transfer device. The printer includes a requesting portion configured to, when user authentication of a user of the terminal is successful, request the print data from the transfer device, and a printing portion configured to, when the user authentication is successful, perform the printing based on the print data received from the transfer device or the terminal.
