This is a stapling and hole-punch finisher accessory for Lexmark's large-format enterprise printer and MFP lines — compatible with the MS911, MX91x, CS92x and CX92x series — rather than a printer in its own right. It attaches to a compatible base machine to add in-line finishing to printed output: stapling completed sets together and punching either 2-hole or 4-hole patterns for filing, without needing a separate manual finishing step or an external binding machine. This is the kind of accessory corporate print rooms and reprographics departments add when they're producing finished reports, booklets or presentation packs directly off the printer, rather than printing loose pages that still need manual collating and punching afterward.
