Abstract: A non-limiting example method of printing device startup based on computed pen age includes reading a pen manufacturing date encoded in a pen of a printing device. The method includes computing a pen age for the pen of the printing device based on the pen manufacturing date, and selecting a startup level based on the computed pen age.

Abstract: Subsequent to completion of printing on a current media sheet, a pick transmission of the printing device linking a motor of the printing device to a pick roller of the printing device is engaged to load a next media sheet via the motor driving the pick roller. While the next media sheet is being loaded due to the motor driving the pick roller, the current media sheet is ejected via the motor driving an eject roller of the printing device.

Abstract: Examples relating to calibrating printing pens of a print bead assembly in a printer are described. For example, techniques for calibrating a printing pen includes detecting position of a first symbol and a second symbol of a pattern from amongst multiple patterns in an alignment pattern, where each pattern is associated with art ideal deviation and the symbols are printed in a juxtaposed position. The ideal deviation is a predefined value of deviation between the symbols when the printing pen is aligned. Thereafter, determining an actual deviation, due to misalignment in the printing pen, between the symbols. Further the technique includes establishing a relation between the actual deviation and the ideal deviation for the multiple patterns and determining a value of the ideal deviation for a zero value of the actual deviation. The value of the ideal deviation is a corrective value of alignment for the printing pen.
