Printing apparatus, a control method therefor, and a data processing apparatus using said printing apparatus

摘要

The printing apparatus of the invention provides a control command interpreter whereby control commands can be interpreted even in an off-line state. The cause of the off-line state can then be determined while in the off-line state, and the host computer can be notified of the cause. This achieves a high throughput rate printing. The user can cancel the cut-sheet paper insertion wait-state at any time, and determine why an error occurred to enable recovery from the error. This printing apparatus further provides high data reliability, reduces host computer overhead, and is easy to use.
