This is a Z-fold/trifold finishing accessory option for Lexmark's CS/CX94x series printers -- an add-on module that automatically folds large-format output (typically engineering drawings or wide-format documents fed through a compatible finisher) into a Z-fold or trifold pattern for storage or filing, rather than leaving it as a single large flat sheet. It's an accessory/upgrade option rather than a standalone printer, meant to be added to an existing or newly purchased CS94x/CX94x-series device. This catalog listing gives no further detail on capacity or supported paper sizes, so buyers should confirm exact compatibility and specifications with Lexmark's own documentation for the CS/CX94x finisher options before ordering.
