gtex-letter attempts to deliver an easy alternative interface to LaTeX-letter. It is heavily configurable, and it supports multiple letter headers and default letter openings (which are configurable in the rc-file). Users can choose from three different levels of graphical interface complexity. Novice is easy to understand, while expert is straight-forward. There is also a non-interactive mode that makes production of standard-letters very fast. gtex-letter is implemented in Python and based on GNOME.
TeXtrace is a collection of scripts that convert any TeX font into a Type1 .pfb outline font immediately suitable for use with dvips, pdftex, Acroread, and many other programs. The main advantage of using Type1 fonts with TeX is that Acroread renders TeX's bitmap fonts ugly on screen, but it renders outline fonts beutifully and fast.
KBarcode is a barcode and label printing application for KDE 3. It can be used to print everything from simple business cards up to complex labels with several barcodes, such as article descriptions. KBarcode comes with an easy-to-use WYSIWYG label designer, a setup wizard, batch import of labels (directly from the delivery note), thousands of predefined labels, database managment tools, and translations in many languages. Even printing more than 10,000 labels in one go is no problem for KBarcode. Additionally, it is a simple xbarcode replacement for the creation of barcodes. All major types of barcodes like EAN, UPC, CODE39, and ISBN are supported.
