A fixed electrode (16a) at a positive potential is disposed at a place not opposed to a print head and has a dielectric layer (17) on the front surface. A transporting belt (10) has a conductive layer (11) at a negative potential, a dielectric layer (12) on the front surface, and holes (13, 14) through which the lines of electric force from the fixed electrode extend. The lines of electric force from the dielectric layer of the fixed electrode through the holes polarize a sheet (S) placed on the dielectric layer (12) and the dielectric layer (12). Therefore, the sheet is electrostatically clamped onto the transporting belt near the holes. When the transporting belt is moved along the fixed electrode, the sheet is transported while being electrostatically clamped by the transporting belt. The sheet transporting device has a simple structure and stable holding force and transportation speed, and does not cause ink droplet deflection due to an electric field.

An in jet printer comprising a belt conveying section (106) for conveying a print sheet (2) on a circulating conveyance belt (106a), a pair of resist rollers (111) and a BU roller (112) for feeding the print sheet (2) while flexing it in the conveying direction, and first and second ink jet heads (104a, 104b) for ejecting ink toward the print sheet, wherein the ink jet head (104b) ejects ink darker in color than ink ejected from the ink jet head (104a). The ink jet head (104b) is located at a position farther than the arriving position of the print sheet (2) when the print sheet (2) is displaced from the conveyance belt (106a) in the conveying direction as the elasticity of the print sheet (2) due to flexure exceeds adhesion between the print sheet (2) and the conveyance belt (106a), and the ink jet head (104a) is arranged between the ink jet head (104b) and the BU roller (112). Consequently, print quality can be sustained with high speed printing by using an ink jet head and reduction in printer size achieved.

A printer server is connected to a plurality of client PC via a network for managing print data transmitted from the client PC and outputting a print instruction to a printer. The printer server performs an administrator authentication according to an environment variable of the client PC which has made an access or a predetermined password. When the client PC is authenticated as an administrator, the printer server gives an administrator right such as job display and job operation of job information to the client PC. When the client PC is not authenticated as an administrator, the printer server limits the job display and job operation according to the administrator right for the access to the job information from the client PC.
