About formats

OXPS (Open XPS) is a fixed-layout document format standardized as ECMA-388 in June 2009, representing an evolution of Microsoft's original XPS specification. The format packages fixed-layout pages, fonts, images, and metadata in a ZIP-based Open Packaging Conventions container — the same packaging framework used by DOCX, XLSX, and other Office Open XML formats. Each page is described using an XML markup language that specifies paths, glyphs, images, and canvas elements with precise coordinates, producing documents that render identically regardless of the viewing device or printer. OXPS incorporated several changes from the original XPS: the use of JPEG XR for high dynamic range images, support for the Open Packaging Conventions 2nd edition, and alignment with the Ecma standardization process. Windows 8 and later generate OXPS (rather than XPS) when printing to the Microsoft XPS Document Writer. One advantage is standards-based document fidelity — as an Ecma standard, OXPS provides a vendor-neutral, fully specified format for documents that must look identical everywhere they are rendered, essential for legal filings, regulatory submissions, and archival records. The fixed-layout model is another strength: unlike reflowable formats, OXPS documents preserve exact page composition including precise glyph positioning and vector graphics. Built-in support in Windows and the .NET framework provides native viewing and creation capabilities without third-party software.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.
