Apparatuses, computer-implemented methods, and computer program products for improved print position compensation
Embodiments of the disclosure provide for improved print position compensation, for example to improve accuracy of print job(s) performed by a printer. The print position compensation enables an offset of the time until printing occurs on a print media to account for changes and/or erroneous movement in a print media, such as due to slippage and/or other results of a force applied to the print media. Particular embodiments determine data values derived both for an output phase and a retraction phase of the printer's operation. Various embodiments generate a print position compensation based on sensor-based edge position distances determined during each of a media output phase and a media retraction phase. Alternatively or additionally various embodiments generate a print position compensation based on sensor-based media movement phase timestamp differentials determined during each of a media output phase and a media retraction phase.
1. An apparatus comprising at least one processor and at least one memory having computer-coded instructions stored thereon that, in execution with the at least one processor, cause the apparatus to:
determine, via a sensor, a first distance value and a second distance value based on detection of at least one edge of a printable portion of a print media during a media output phase and a media retraction phase of printer operation, respectively, wherein the first distance value and the second distance value corresponds to the distance between (i) the at least one edge of the printable portion and (ii) a print head of the apparatus; and
generate a print position compensation based at least in part on the first distance value and the second distance value.
2. The apparatus according to claim 1 , wherein the apparatus is further caused to control activation of a light source during at least one of the media output phase and the media retraction phase to produce light rays that shine through the print media.
3. The apparatus according to claim 1 , wherein the apparatus is further caused to generate the print position compensation based at least in part on a divisor factor associated with the first distance value and the second distance value.
4. The apparatus according to claim 1 , wherein the apparatus is further caused to:
initiate a print operation based at least in part on the print position compensation.
