Abstract: The present invention relates to a method for controlling the ink feed in a printing press which processes printing substrates (12) and features at least one inking unit and one computer and to a device for carrying out the method. The present invention is characterized in that the computer knows at least the physical properties of printing ink and/or printing substrates (12) as data, that the stored data is read into an ink control model which is stored in the computer, and that the optimum settings with regard to the ink feed are made on the basis of this ink control model before the start of printing or during the printing process.

Abstract: The disclosure relates to methods and apparatus for printing a document from a computer workstation to a multifunction peripheral. Upon receiving a print command, the computer workstation determines whether the multifunction peripheral prints pages in a face-up or a face-down configuration. If the multifunction peripheral prints pages in a face-down configuration, the workstation invokes a printer driver to send the pages of the document to a print controller in reverse order. The print controller processes an initial portion of the document and sends the initial portion to the multifunction peripheral for printing. The multifunction peripheral prints the initial processing portion of the document while the controller processes the remainder of the document.

Abstract: A method of printing using a thermal print head comprises a plurality of printing elements arranged generally in an array each of which may selectively be energised and de-energised under the control of a control means to transfer pixels of marking medium from a carrier onto a substrate or to activate pixels on a sensitive substrate, the method comprising providing to the control means data dependent on the nature of the image to be printed which would enable the image having an image length L to be printed as a matrix of pixels at a linear resolution of C where C is the number of image columns per unit length in the direction of printing, wherein the method comprises causing relative movement between the print head and the substrate such that the print head relatively traverses the substrate the image length L in an available time T whilst the print head performs E thermal cycles to print the image, and the control means manipulating the data so that the image is printed with the print head omitting or repea
