Abstract:
A system is provided in which printer driver update work is not required, and in addition, print queue creation work can be hidden. When a virtual printer driver is installed, a generic printer driver is installed in the system without creating a print queue. Then, for execution of printing, the installed generic printer driver is used to create the print queue, and a print job is input to the print queue.
Abstract:
An information processing apparatus working in pause states containing at least both a suspension state and a hibernation state, may include a time counting unit for counting time elapsed in the suspension state from a transition to the suspension state, and a transitioning unit for transitioning to the hibernation state if the elapsed time has exceeded a predetermined period of time.
Abstract:
A printing control apparatus is provided which can produce an appropriate copy-forgery-inhibited pattern image by adding a monochrome copy-forgery-inhibited pattern even if monochrome mode printing is performed in the condition in which a color copy-forgery-inhibited pattern is set. When the monochrome mode printing is performed in the condition in which the color copy-forgery-inhibited pattern is set, and if the copy-forgery-inhibited pattern color is output with its color unchanged, the color is not converted into 100% black. Considering this, when a forced monochrome mode is selected, even if the user's setting for the copy-forgery-inhibited pattern is color, the color is changed to monochrome (black) before output. If the designated copy-forgery-inhibited pattern setting is for color, the designated copy-forgery-inhibited pattern setting is changed to the monochrome copy-forgery-inhibited pattern setting so that the printing processing is performed in the monochrome mode using the designated copy-forgery-inhibited pattern setting.
Abstract:
An image processing apparatus performs a density adjustment process for generating an image containing a copy-forgery-inhibited pattern image for warning against the use of copy products. To help users to easily adjust the density of a latent image portion and a background portion in the copy-forgery-inhibited pattern image, the image processing apparatus determines a density relationship of the latent image portion and the background portion by performing a plurality of adjustment operations, in combination, different in the amount of adjustment relating to the range of variable density in at least one of the latent image portion and the background portion, and sets, based on the density relationship, the density data of each of the latent image portion and the background portion in the data of the copy-forgery-inhibited pattern image.
Abstract:
An information processing apparatus generates printing image data of a printing image and copy-forgery-inhibited-pattern-image data of a copy-forgery-inhibited pattern image to be added to the printing image. The copy-forgery-inhibited pattern image includes a latent image and a background image. The apparatus includes a selecting unit and a printing-data generating unit. The selecting unit selects either the transparent-printing designation or overlay-printing designation, the transparent-printing designation is used for generating printing data so that the copy-forgery-inhibited pattern image is superimposed on the printing image, and the overlay-printing designation is used for generating printing data so that the printing image is superimposed on the copy-forgery-inhibited pattern image. The printing-data generating unit generates printing data based on the printing designation selected by the selecting unit.
