Abstract
An ink jet printer including a print head having nozzles for jetting ink for a length corresponding to dimensions of a recording medium in the direction perpendicular to the conveyance direction, a recording medium conveying section, a print head driving section that makes the print head to jet ink synchronizing with conveyance of the recording medium, a speed setting section to set printing speed based on the instruction of a user, and a control section that determines conveyance speed of the recording medium based on the printing speed established by the speed setting section, and determines a time interval from the completion of printing of one page to the start of printing for the next page, and makes the conveying section to convey and supply the recording medium at the determined conveyance speed and time interval.
Claims25
An ink jet printer, comprising:
- a print head having plural nozzles for jetting ink over a length corresponding to a dimension of a recording medium that is perpendicular to a conveyance direction of the recording medium;
- a recording medium conveying section that supplies the recording medium to the print head and conveys the recording medium under the print head;
- a print head driving section that drives the print head to jet ink in synchronization with conveyance of the recording medium;
- a speed setting section to set a printing speed based on an instruction of a user;
- and
- a control section, which determines:
- (i) a conveyance speed of the recording medium under the print head based on the printing speed established by the speed setting section, and (ii) a time interval from completion of printing of one page to a start of printing of a next page, and which controls the recording medium conveying section to convey and supply the recording medium at the determined conveyance speed and the determined time interval.

- a recording medium conveying section that supplies the recording medium to the print head and conveys the recording medium under the print head;
- a print head driving section that drives the print head to jet ink in synchronization with conveyance of the recording medium;
- a speed setting section to set a stepless printing speed based on an instruction of a user;
- and
- a control section, which determines a conveyance speed of the recording medium under the print head based on the printing speed established by the speed setting section, such that the determined conveyance speed is not in a predetermined speed range, and which controls the recording medium conveying section to convey the recording medium at the determined conveyance speed.
