Abstract: A printing device has a replaceable component. The printing device uses the replaceable component when printing. The replaceable component at the printing device is measured to determine its availability. A requirement is calculated as to what is needed from the replaceable component in order to print a print job at the printing device. The print job is transmitted to the printing device when the availability is not less than the requirement but not when the availability is less than the requirement.

Abstract: Communication system having a multiprocessor system serving the purpose of central control. Multiprocessor systems are used in communication systems for the purpose of central control. Care must thereby be exercised to ensure that the jobs/messages arriving from a periphery according to the FIFO principle are in turn deposited in the original sequence after being handled by processes being executed on the processors. A coordination procedure required for this purpose thereby uses a holding table. The logical sequence of jobs/messages is thus assured during the processing in the multiprocessor system.
