Method and system to reduce printing errors in a mail processing device

摘要

Method for reducing printing errors during printing of mail items has the following steps: generation of encoder impulses corresponding to the relative movement between print and print medium; up and down counting to determine a state with reduced time interval between encoder impulses; execution of direct memory access (DMA) for accessing binary pixel data and; implementation of a print cycle for the data string with subsequent DMA access to the data string during subsequent print cycles. An independent claim is made for an arrangement for reducing printing errors during printing of moving mail items with a moving print head.
