There is provided an image reading device, which is provided with an illuminating unit that illuminates an object, a reading unit that forms an image of the object based on light from the object, and an illumination prohibition unit that prohibits the illumination unit from illuminating the object if the illumination prohibition unit receives a command for changing to a code reading mode in which a code formed by a pictorial pattern displayed on a screen of a device is read as the object.

In a printer connected to a network, email appended with link information is prepared for enabling an administrator to access information about the printer network terminal. The email is transmitted to the administrator terminal at a predetermined timing. Then, the administrator terminal accesses the information based on the link information appended to the email. As such, when a problem occurs in the printer, operations for resolving the problem can be quickly undertaken by the administrator.

In order to prevent unnecessary APIPA process from being executed in a LAN environment which does not adopt APIPA, an ICMP echo request for a predetermined IP address is broadcast. Whether there are more than N apparatuses using APIPA is checked based on the replies, and if there are, IP address setting by APIPA is executed. In a LAN environment which adopts APIPA, whether the IP address to be assigned to an apparatus is already being used by another apparatus is checked. If the date and time when the another apparatus was assigned the IP address is earlier than the date and time when the apparatus was assigned the IP address, APIPA is executed to decide the IP address of the apparatus.

In each of personal computers, information concerning an application software to process image data sent to a scanner is received. A dialog box is displayed and a user entry is made as to whether transmission is permitted or not. When transmission is rejected by the user, a notice of the rejection of transmission is given to the scanner. When transmission is permitted by the user, the application software is started and a notice of the permission of transmission is given to the scanner. Then, image data is received from the scanner and processed by the started application software.

A contents providing system includes a communication unit, a print control unit, an expendable amount deriving unit and an expendable amount storing control unit. The communication unit communicates with a contents server having contents data. The print control unit controls a printer to print the contents data and output a printed material imaging the contents data if the communication unit receives the contents data from the contents server. The expendable amount deriving unit derives an amount of an expendable item required for imaging the contents data in the printer. The expendable amount deriving unit derives the amount of the expendable item in accordance with a size of an image printed by the printer. The expendable amount storing control unit stores information representing the amount of the expendable item derived by the expendable amount deriving unit in a memory unit.

A wireless LAN system in which data communication between a wireless station whose connection method as a method for wireless connection can be set to one of a plurality of connection methods and a wireless access point whose connection method has been preset to one of the connection methods is made possible by setting the connection method of the wireless station to a method identical with the connection method of the wireless access point.

The standard brightness region is displayed with input values of zero. The comparison brightness region is displayed with an input value which is variable in the range of 0 to 255. The standard brightness and comparison brightness regions are displayed next to each other in the display. The input value is changed from zero. A first black point is determined as an input value which causes the comparison brightness region to first appear distinguishable from the black regions of the standard brightness regions. Then, the input value is changed from 255. A second black point is determined as an input value which causes the comparison brightness region to first appear indistinguishable from the black regions of the standard brightness regions. Then, a black point is calculated as an average of the first and second black points.

In S100, multilevel density data C, M, Y, and K for a subject pixel are read out from the data recording medium. Then, the total ink density ND is calculated in S110. It is judged whether or not the total ink density ND is higher than the predetermined limit value L1. When the total density ND is not higher than the value L1 (no in S120), the original density data C, M, Y, and K for the subject pixel are subjected to the binarization process in S140. When the total density ND is higher than the value L1 (yes in S120), on the other hand, the value of the multilevel data for each chromatic color component is reduced through an ink density reduction process in S130. The thus obtained reduced multilevel data C3, M3, and Y3 and the black multilevel data are subjected to the binarization process in S140.
