leegisker/ecofont-script

This is a Python command-line script that converts documents into an ink-saving format for printing. The idea is simple: instead of filling each letter solid with ink, the script redraws the text as outlines only, just the strokes of each character, not the filled interior. This technique, the same approach used by the Ryman Eco font, can save up to 33% of printer ink while the text still looks normal on screen. You drop your files into a folder called Conversion Folder, run the script, and the converted files appear in a Converted folder automatically. The script supports PDF files, Word documents (.docx), and Markdown files (.md). For PDF files it works by decompressing each page's content stream, stripping any existing text rendering settings, and inserting a stroke-only rendering command around each block of text, then recompressing the result. For Word and Markdown documents, the script first renders the content to a temporary PDF using ReportLab, then applies the same eco transformation. You can also run it directly on specific files, point it at a custom folder, or use a dry-run mode to preview what would happen without actually changing anything. The stroke width, meaning how thick the character outlines are, is adjustable with a command-line flag, letting you balance ink savings against readability. Dependencies are pypdf, reportlab, and optionally python-docx for Word support, and a flag lets the script install any missing packages automatically. The tool requires Python 3.10 or newer.
