Abstract: Examples include a method comprising preparing nominal firing data of a print job for a first printhead die and for a second printhead die of a page wide array printer. The first printhead die is located downstream from the second printhead die along a media path of the printer, the printhead dies being offset along the media path by an offset distance. The methods comprises starting printing by applying the nominal firing data to the printhead dies; receiving a print job interruption request during printing of the print job; and in response to receiving the job interruption request, modifying the nominal firing data to obtain modified firing data for interrupting printing using the first printhead die while continuing printing using the second printhead die during a specific time period after the first printhead die interrupted the printing, the specific time corresponding to the offset distance.
