In a printer of the present invention, an EEPROM that carries out sequential access and has a relatively small storage capacity is applied for storage elements mounted on both black and color ink cartridges, which are detachably attached to the printer. Pieces of information relating to each ink cartridge, for example, pieces of information on remaining quantities of respective inks in the ink cartridge, are stored in the storage element of the ink cartridge. A format of addressing adopted in the storage elements of the ink cartridges Is different from that adopted in an EEPROM incorporated in a printer main body of the printer. A control IC provided in the printer accordingly converts the storage format of addressing, before writing the information into the storage elements of the ink cartridges. In the printer, a RAM is mounted with the control IC on a carriage, and the pieces of information to be written Into the storage elements of the ink cartridges are temporarily registered in the RAM. The pieces of information are then written into the respective storage elements of the black and color ink cartridges, for example, at a timing of a powe-off operation. The signal lines and the memory used in the course of writing the information into the storage elements are identical with the signal lines, through which print data are transmitted to a print head mounted on the carriage of the printer, and the memory, in which the print data are stored. The arrangement of the present invention reduces the manufacturing cost of the ink cartridge and also enables size reduction of the whole printer.< / PTEXT>

Techniques are disclosed for performing thermal history control in a thermal printer in which a single thermal print head prints sequentially on multiple color-forming layers in a single pass. Each pixel-printing interval may be divided into subintervals, which may be of unequal duration. Each sub-interval may be used to print a different color. The manner in which the input energy to be provided to each print head element is selected may be varied for each of the subintervals. For example, although a single thermal model may be used to predict the temperature of the print head elements in each of the subintervals, different parameters may be used in the different subintervals. Similarly, different energy computation functions may be used to compute the energy to be provided to the print head in each of the subintervals based on the predicted print head temperature.

Methods for ultrashort pulse laser processing of optically transparent materials. A method for scribing transparent materials uses ultrashort laser pulses to create multiple scribe features with a single pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. This enables clean breaking of transparent materials at a higher speed than conventional techniques. Slightly modifying the ultrashort pulse laser processing conditions produces sub-surface marks. When properly arranged, these marks are clearly visible with side-illumination and not clearly visible without side-illumination. In addition, a method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. The ultrashort pulse duration causes nonlinear absorption of the laser radiation, and the high repetition rate of the laser causes pulse-to-pulse accumulation of heat within the materials. The laser is focused near the interface of the materials, generating a high energy fluence at the region to be welded. This minimizes damage to the rest of the material and enables fine weld lines.

When the cassette is loaded into the thermal printer, the outer surface of the cassette and an inner wall of the thermal printer cooperate to form a paper path therebetween through which each of the sheets of print paper is advanced from the paper tray to the thermal head.

The input color values for each colorant then are independently adjusted to reduce the error value to a predetermined degree.
