Abstract: According to examples, a printer may include a processor and a memory on which is stored machine readable instructions that may cause the processor to access an instruction to print a print job of a user and determine whether the user is moving toward the printer. In response to a determination that the user is moving toward the printer, the instructions may cause the processor to initiate printing of the print job.
