1. An inkjet printer comprising:
at least one printhead; and
a controller operatively connected to the at least one printhead and a print job queue, the controller being configured to:
identify a thermal load on the at least one printhead that will occur during execution of a print job in the print job queue using print job parameters for the print job, ink image content data for the print job, and environmental condition measurements received from sensors in the printer;
determine whether the identified thermal load will raise a temperature of the at least one printhead above an upper threshold of a predetermined temperature range;
identify a remedial action that reduces the identified thermal load so execution of the print job will not raise the temperature of the at least one printhead above the upper threshold of the predetermined temperature range;
perform the identified remedial action and the remedial action is a manipulation of the print job queue; and
not identify a remedial action when the identified thermal load will not raise the temperature of the at least one printhead above an upper threshold of a predetermined temperature range.
