foo2slx is a printer driver for printers that use the Software Imaging K.K. SLX wire protocol for their print data, such as the Lexmark C500n. This driver uses Ghostscript to perform all of the heavy lifting (image processing). There are six major components to the foo2slx printer driver.
foo2hiperc is a printer driver for printers that use the HIPERC wire protocol for their print data, such as the Oki C3400n and the Oki C5500n. It uses Ghostscript to perform all of the heavy lifting (image processing). There are five major components: foo2hiperc (the page image to protocol conversion engine of the driver); foo2hiperc-wrapper (runs ghostscript and foo2hiperc in a pipeline); icc2ps (converts an ICM color profile to a Postscript CRD, which is then fed into Ghostscript before the user's Postscript program); foomatic-db (foomatic database entries that describe the supported printers and their options so that printer spoolers know how to access the printer using foo2hiperc-wrapper); and hipercdecode (a tool for developers to inspect HIPERC streams).
flpsed is a WYSIWYG PostScript annotator. You can't actually edit existing documents, but you can add arbitrary text lines to existing documents. Added lines can later be re-edited with flpsed. Using pdftops, flpsed can import PDF documents and also add text to them. It is useful for filling in forms, adding notes, etc. In batch mode, it can be used to automate form filling.
Xpdf is a viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities. It runs under the X Window System on UNIX, VMS, and OS/2. The non-X components (pdftops, pdftotext, etc.) also run on Win32 systems, and should run on pretty much any system with a decent C++ compiler. Xpdf is designed to be small and efficient. It can use Type 1 and TrueType fonts.
PDFreactor is a formatting processor to convert HTML and XML to PDF. It uses Cascading Style Sheets (CSS) to define page layout and styles. It allows you to dynamically generate PDF documents such as invoices, delivery notes, shipping documents, or print versions of Web content on-the-fly. Vector graphics (SVG), barcodes, MathML, XSLT, and CMYK colors are supported. All common J2EE application servers are supported. Complete .NET, PHP, Perl, Python, and Ruby APIs are included. Direct integration into automatic build processes using Apache Ant is also possible.
