Data printing and outputting apparatus
First Claim
1. A data printing and outputting apparatus, comprising:
- a host device; and
a printer, connected with the host device through a communication line, for printing output data,wherein said printer includes,received data storing means for storing print data sent from the host device;
trouble detecting means, provided in said printer, for detecting trouble with the printer, and for outputting a trouble condition signal indicative of conditions of the detected trouble;
trouble analyzing means for monitoring a printing operation of the printer, and for judging based on the trouble condition signal if the trouble with the printer is relatively minor and does not take a relatively large amount of time to solve or relatively major and may take a relatively large amount of time to solve; and
communication controlling means for maintaining communication between the host device and the printer when the trouble is judged to be relatively minor by the trouble analyzing means based on the trouble condition signal sent from the trouble detecting means, and for stopping the communication when the trouble is judged to be relatively major.

Abstract
A data printing and outputting apparatus has a host device, and a digital copying machine connected with the host device through a communication line for printing and outputting data. The control section of the digital copying machine, monitoring the printing operation by the digital copying machine, maintains the communication between the host device and the digital copying machine when the trouble with the digital copying machine is a minor one which does not take time to solve, and stop the communication between the host device and the digital copying machine when the trouble is a major one which takes time to solve. The data printing and outputting apparatus, thus, can increase host device'"'"'s job efficiency by reducing its workload in the communicating operation between the host device and the digital copying machine.

7. A data printing and outputting apparatus, comprising:
-
a host device; a printer, connected with the host device through a communication line, for printing and outputting data; transmission data storing means, provided in the host device, for storing print data to be sent to the printer, and for deleting the print data after the print data is sent to the printer; host device-side communication controlling means, provided in the host device, for controlling the sending of the print data from the transmission data storing means to the printer; received data storing means, provided in the printer, for storing received print data sent from the host device, and for maintaining storage of the print data, subsequent to resending of the print data to the host device; trouble detecting means, provided in the printer, for detecting trouble with the printer; and printer-side communication controlling means, provided in the printer, for resending, back to the host device, the print data stored in the received data storing means when trouble is detected with the printer by the trouble detecting means, wherein at least one of the host device-side and printer-side communication controlling means stops the communication between the host device and the printer subsequent to completion of the data sending and receiving between the host device and the printer. - View Dependent Claims (8, 9, 10, 11, 12)

13. A data printing and outputting apparatus, comprising:
-
a host device; a printer, connected with the host device through a communication line, for printing print data sent from the host device in accordance with a selected mode, the mode being selected from a rough mode with low print quality and a non-rough mode with relatively higher print quality; data error detecting means, provided in the printer, for detecting an error occurring in the print data at the printer; and print controlling means, provided in the printer, for maintaining the printing operation at the printer when the error of the print data is detected by the data error detecting means and the rough mode is the selected mode. - View Dependent Claims (14)

17. A data printing method for a printer connected to a host device through a communication line, comprising the steps of:
-
selecting one of a rough mode with low print quality and a non-rough mode with relatively higher print quality; printing, at the printer, print data sent from the host device in accordance with the selected mode; detecting whether or not an error has occurred in the print data at the printer; and maintaining the printing operation at the printer when an error is detected and when the rough mode is the selected mode. - View Dependent Claims (18, 19, 20)
