Abstract
The positioning of image data written along a laser beam scan path in the scan direction, e.g., the margin and/or line length is adjusted in a manner that compensates for changes in the laser beam scan path as a result of one or more operating conditions, such as changes in temperature. Further, the positioning of image data in the process direction may be adjusted in a manner that compensates for changes in the laser beam scan path as a result of the one or more operating conditions.
