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.

Provided is a process for producing a surface emitting laser including a surface relief structure provided on laminated semiconductor layers, including the steps of transferring, to a first dielectric film, a first pattern for defining a mesa structure and a second pattern for defining the surface relief structure in the same process; and forming a second dielectric film on the first dielectric film and a surface of the laminated semiconductor layers to which the first pattern and the second pattern have been transferred. Accordingly, a center position of the surface relief structure can be aligned with a center position of a current confinement structure at high precision.

The present invention realizes a network printing system capable of accumulating and chasing printed data. Further, by providing a job chasing function on the printer driver side, detailed setting can be done to extract history information of the job chasing function. The detailed setting to extract history information to chase a job can be done only by a specific administrator or user so that the job can be reliably chased, whereas the administrator or user can obtain desired history information. Accordingly, a precise jog chasing system can be established.

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.

A vertical cavity surface emitting laser capable of efficiently injecting carries into an active region directly under a photonic crystal mirror is provided. The vertical cavity surface emitting laser includes a first reflective mirror 102 constituting a lower mirror, a second reflective mirror 112 constituting an upper mirror, and an active layer 106 provided between the reflective mirrors on a substrate 100. The second reflective mirror 112 includes a periodic refractive index structure periodically arranged in a plane parallel to a surface of the substrate, which structure is composed of a first medium 1100 having conductivity and a second medium 1102 having a refractive index lower than that of the first medium 1100. A layer structure by a third medium 1104 having a refractive index lower than that of the first medium 1100 is embedded in the first medium 1100 on the lower side of the periodic refractive index structure.
摘要:
Disclosed is a printing control apparatus in which a printing instruction is once converted into an intermediate code format and then converted into a printer control command, and which can correctly print an embedded font. In this invention, a spooler for converting a printing instruction into an intermediate code format and storing this intermediate code format detects the presence/absence of an embedded font on the basis of font attributes contained in the printing instruction. If an embedded font is detected, the spooler acquires the embedded font (S3.3) and spools the font by the intermediate code format (S3.4). The despooler registers the spooled embedded font in a graphic engine (D3), and a printer driver generates a control command by using the registered embedded font (Drv3.1).
