Abstract: An example device includes: a print engine including a fuser; an ambient temperature sensor; a memory storing a plurality of curves that relate, for given respective ambient temperatures, respective time periods for the fuser to heat to a fusing temperature, to respective factors associated with cooling of the fuser; and a processor The processor is to: detect a current ambient temperature using the ambient temperature sensor; select a curve, from the plurality of curves, using the current ambient temperature; determine a current factor associated with cooling of the fuser; and control the fuser to heat to the fusing temperature based on a respective time period determined from the curve and the current factor associated with cooling of the fuser.

Abstract: An example non-transitory machine-readable medium includes instructions that, when executed by a processor, cause the processor to receive a job to print multiple copies of a document, process a page of the document to obtain a processed page, initiate printing of the processed page at a printer, transmit via a network the processed page to network storage, and, when ready to print a subsequent copy of the page of the document, retrieve via the network the processed page from the network storage.

Abstract: According to examples, an apparatus may include a processor and a memory on which are stored computer-readable instructions that, when executed by the processor, may cause the processor to determine a property of dust based on information associated with the dust in a printing device. The processor may classify the dust according to the determined property of the dust and may determine a predicted failure mode associated with the dust classification. The processor may output an instruction associated with the predicted failure mode.
