Abstract: In a printing system, a print data generating unit generates first print data of an original image that includes a bar code storing a disposing position and a particular sub-image. The particular sub-image is disposed at the disposing position when the original image is read and processed. A first printing unit prints the original image on a first recording medium based on the first print data. A controller controls a reading unit to read the original image printed on the first recording medium and to retrieve the disposing position and the particular sub-image from the bar code. The controller generates second print data of a processed image in which the retrieved particular sub-image is disposed at the retrieved disposing position. The controller controls the second printing unit to print the processed image on a second recording medium based on the second print data.

Abstract: A print data generating device comprises a retrieving unit, a bar code data generating unit, and a print data generating unit. The retrieving unit is configured to retrieve image data of an original image. The bar code data generating unit is configured to generate, based on the image data of the original image, data of at least one bar code that stores the original image. The print data generating unit is configured to generate, based on the image data of the original image and the data of the at least one bar code, print data of a print image that includes the at least one bar code arranged on one page and the original image arranged on one or more pages.

Abstract: A liquid droplet jetting apparatus comprises a liquid droplet jetting head which jets liquid droplets, a storage tank which stores a liquid to be jetted by the liquid droplet-jetting head, a tube which connects the liquid droplet jetting head and the storage tank, and a liquid-state detecting mechanism which detects a state of the liquid contained in the tube at a plurality of positions in a longitudinal direction of the tube.

Abstract: An ink cartridge includes a support member, and a rotatable member connected to the support member. The rotatable member includes a pivot portion formed at a point of connection between the support member and the rotatable member, and a signal blocking portion. The signal blocking portion is disposed within an inner space of a translucent portion. The rotatable member also includes a float portion disposed within an ink chamber. The float portion is positioned between the signal blocking portion and the pivot portion, and the float portion is configured to move between a first position and a second position based at least on an amount of ink disposed within the ink chamber.

Abstract: There is disclosed a printing apparatus implemented as a laser printer capable of changing the print format when outputting print data. When the operator changes the print format at the printer, the CPU changes the print data in a text buffer of a built-in RAM according to the changed print format, the data being converted into image data in a dot pattern for storage into an image buffer. The operator then pushes a reprint key, causing the CPU to read the pages of print data stored in the image buffer for outputting to a laser printer engine via a printer engine interface for reprinting. The printing apparatus allows the print format to be changed easily for efficient reprinting of the last print data in the new format without the need for the host computer to supply the same print data again.
