Abstract: A system and a method for providing customized graphical user interfaces and/or screen layouts in computer systems. A web browser is nested in an application. XML text files are used to describe one or more user interfaces. The application software uses the information (e.g., source code) in the XML files to generate the user interface. For dynamic updates this may be done “on the fly,” allowing changes to the files and the addition/deletion of files even at run-time. The general layout of a user interface is defined in an HTML-based template. The details of the user interface are generated by software which retrieves a selected XML display/editor template text file, populates the XML display/editor text with current system data, converts the XML data to HTML, and then populates the HTML template to produce an HTML-based text for display. The user interface is then generated from the HTML-based display text by the web browser.

Abstract: The present invention involves a new system and process for automatically and dynamically laying out elements within an overall window of a graphical user interface by using dynamically resizable frames, i.e., “FlowFrames” disposed within the window. FlowFrames are automatically and dynamically sized and positioned within the window, while one or more other frames, i.e., “child frames,” representing one or more conventional controls, nested within the FlowFrames are also sized and positioned within the window as the window is generated or resized. In particular, each FlowFrame arranges its children horizontally in a row, but dynamically wraps them to one or more additional rows and positions them in accordance with predefined relationships between the children, where they cannot all fit into the same row. Further, the size of each FlowFrame is computed hierarchically from its children up to the overall window and then back down to the individual children.

Abstract: It is an object of the present invention to provide an ink jet printing apparatus which sufficiently heats a head even in a low-temperature environment, which enables a proper image to be printed by stably ejecting ink, and which can be inexpensively and simply constructed. According to the present invention, if the detected temperature of a printhead is lower than a first heating threshold temperature higher than the first heating threshold, a heating mode in which the printhead can be heated is set before a printing operation. Further, when the heating mode is set and the detected temperature of the printhead is lower than the heating threshold temperature, a heating unit heats the printhead. Consequently, even in a low-temperature environment, the heating operation keeps ink good and suitable for printing.

Abstract: Two lines extending in the main scanning direction build a set of lines (L1, L2) each of which is formed by a plurality of dots. Assignment is alternately executed to preceding scanning and subsequent scanning so as to allow each of the lines (L1, L2) formed by a number of pixels (P1, P2, P4, P3, P5, P6, P8, P7, - - - ) to extend along a snake movement-like route. Thus, dots located adjacent to each other in the auxiliary scanning direction are not formed by same scanning, and a quantity of ink spreading on a recording medium without penetration of the ink through the latter can be reduced. Consequently, there few arises stripe and fluctuation in density, whereby an excellent quality of image having sharp edge portions can be obtained without any occurrence of a problem attributable to the presence of unfixed ink.

Abstract: When a printing apparatus performs printing using dark and light inks, a large variation in density caused by a rapid decrease in ink applying rate is prevented, thereby enabling proper density reproduction. More specifically, when for example, green hues of different densities are printed, light cyan ink is used between points corresponding to a variation of color from white to green. Furthermore, after the maximum saturation point, light cyan ink is used in addition to the dark cyan ink. This prevents the total applying rate from decreasing rapidly near the maximum eaturation point.

The cover includes a substantially planar top surface positioned over the toe-end of the detachable printer component when the printer component is fully installed on the mounting portion, such that the cover extends over the printer component only by an amount that precludes the cover from interfering with a toe-heel installation process.
