1. A printing apparatus for performing printing corresponding to at least one of print data and control commands provided from a host device and for providing the host device with a plurality of state of said printing apparatus, said printing apparatus comprising:
- a plurality of state detection means for detecting each of the states, each of the state detection means belonging to at least one of a plurality of groups;
state change detection means for detecting a change in the state detected by said state detection means; and
state notification means for providing in accordance with said state change detection means to said host device with at least all the states detected by said state detection means belonging to only a predetermined one of the detector groups containing said state detection means detected by said state change detection means.

Abstract
This printing apparatus is provided having a regular status data generating circuit for regularly generating status data. An automatic status selection and transmission circuit selects the status condition to be transmitted by the automatic status transmission operation, and a status data comparator compares the status data. By executing the automatic status selection and transmission command, the status is thereafter transmitted each time the selected status changes.
