It uses the Ghostscript file format converter and RedMon printer redirection software. [5] According to its documentation, PrimoPDF has the following features: PrimoPDF supports creation profiles (Screen, eBook, Print, Prepress, and Custom) to determine file quality, resolution, and size. Can append output to an existing PDF file.
The embedded firmware of a printer could thus eliminate the need to install any driver on a computer, by accepting print data in a general purpose format (e.g. PDF) via a networking protocol. Despite some efforts to standardize various stages of the printing pipeline, printer interfaces are largely still very proprietary and manufacturer-specific.
It stated that PDF files created were not searchable, tended to be larger than produced by other programs, and that conversion was rather slow. [3] It is not limited to PDF, also producing BMP, JPEG, PCX, PNG, and TIFF files. It offers quality settings for screen, printer, ebook, and prepress.
PDF 2.0 defines 256-bit AES encryption as the standard for PDF 2.0 files. The PDF Reference also defines ways that third parties can define their own encryption systems for PDF. PDF files may be digitally signed, to provide secure authentication; complete details on implementing digital signatures in PDF are provided in ISO 32000-2.
A virtual printer is a piece of computer software whose user interface and API resembles that of a printer driver, but which is not connected with a physical computer printer. A virtual printer can be used to create a file which is an image of the data which would be printed, for archival purposes or as input to another program, for example to ...
A variation on the dot matrix printer was the cross hammer dot printer, patented by Seikosha in 1982. [37] The smooth cylindrical roller of a conventional printer was replaced by a spinning, fluted cylinder. The print head was a simple hammer, with a vertical projecting edge, operated by an electromagnet.
Digital printing is a method of printing from a digital-based image directly to a variety of media. [1] It usually refers to professional printing where small-run jobs from desktop publishing and other digital sources are printed using large-format and/or high-volume laser or inkjet printers.
A GTK+ dialog box for printing to either a virtual printer (to create a PDF or PostScript file) or a physical printer. In computing a virtual printer is a simulated device whose user interface and API resemble that of a printer driver, but which is not connected to a physical computer printer.
