Questions tagged [output-routine]
{output-routine} is about questions regarding the output routine, a basic element of TeX processing which is automatically called at different occasions (e.g., at insertions like footnotes or floats) and finally makes up the contents of a page for shipout after a page break has occurred. Headers and footers as well as floats, margin paragraphs and footnotes are added here.
