1. A method for print alignment by a continuous feed printer, comprising:

  • detecting, by a sensor of a printer separated from a print head of the printer by a distance in the direction of travel of the printing medium, a first line of a pattern on a non-printing side of a printing medium, the pattern comprising two non-parallel lines separated by a predetermined distance at a predetermined position of the printing medium;

    advancing, by the printer, the printing medium a first distance;

    detecting, by the sensor, a second line of the pattern;

    identifying, by the printer, a horizontal offset of the printing medium from an expected location of the predetermined position, proportional to the difference between the first distance and the predetermined distance; and

    adjusting the identified horizontal offset by a correction factor proportional to the distance.
