Claim 9:
10. A printing method, comprising:
disposing a substrate on a substrate support of an inkjet printer;
acquiring a first image of a first alignment feature of the substrate using a wide view imaging device of the inkjet printer;
positioning a high magnification imaging device based on the actual position of the first alignment feature and an expected position of a second alignment feature of the substrate;
acquiring a second image of the second alignment feature using the high magnification imaging device of the inkjet printer;
determining an actual position of the second alignment feature in the frame of reference of the inkjet printer based on the second image;
determining a target position of a print region of the substrate based on the actual position of the second alignment feature;
determining a placement error of the substrate;
compensating for the placement error of the substrate; and
controlling the inkjet printer to eject print material from nozzles of a printhead assembly of the inkjet printer onto the substrate in the print region based on the target position of the print region.
