Systems and techniques relating to printing include an apparatus including a base mounting a storage spool to store printing ribbon including a web carrying marking medium, the base mounting a ribbon take-up spool. A ribbon path from the storage to the take-up spool runs through a printing station where there is a print head, and printing is effected at the printing station when relatively moving the head and the substrate with the ribbon interposed between. The apparatus includes a movable ribbon guide member, a ribbon guide member drive device to move the ribbon guide member, and a controller which, during or in between at least some printing operations, controls drive of at least the take-up spool to advance ribbon through the printing station. The controller controls the ribbon guide member in response to an input signal representative of ribbon tension along the ribbon path to adjust the ribbon tension.
