There are three different imaging techniques used by digital cylinder printing machines: multi-pass, single pass, and helical printing.

The move time is inefficient and can lead to stitching artifacts between moves.
This is the bi-directional protocol used between the host server and the printer. It is used to send the page-level data to the printer and to signal errors and accounting information back to the server. The IPDS protocol also allows the server to query a printer's available resources (e.g. available memory, fonts, input trays, etc.).
