Abstract

A facsimile apparatus having a printer interface and a recorder unit usable as a printer, includes an image memory for storing facsimile image data received during an operation as the printer, a key switch for switching an operation mode between a facsimile mode and a printer mode by a switching operation, and a controller for automatically causing the recorder unit to perform an output operation such that the image data stored in the image memory in the printer mode is read out to print received image information by the switching operation of the key switch to the facsimile mode when the facsimile image data is received in the printer mode.

Claims

1. A data communication apparatus comprising:

first receiving means for receiving data from an external terminal through an interface;

second receiving means for receiving data through a line different from the interface;

printing means for printing the data received by said first and second receiving means; and

adding means for adding a predetermined mark to data to be printed by said printing means,

wherein the mark added by said adding means is for discriminating the data received by said first receiving means and the data received by said second receiving means when both sets of data are printed by said printing means, and wherein said adding means adds a time of reception of when the data was received by said second receiving means, and a time of printing of when the data received by said second receiving means was printed by said printing means, these times of reception and printing also being for discriminating the data received by said first receiving means from the data received by said second receiving means, and these times of reception and printing being together printed on the same face of a recording sheet.

2. An apparatus according to claim 1, wherein said printing means visually prints data received by said first and second receiving means, by using a printing agent, and the mark added by said adding means is for detecting the presence/absence of the printing agent.

3. An apparatus according to claim 1, wherein said adding means adds the mark to the data received by said second receiving means.

4. A control method of controlling a data communication apparatus comprising:

a first receiving step, of receiving data from an external terminal through an interface;

a second receiving step, of receiving data through a line different from the interface;

a recording step, of printing the data received in said first and second receiving steps; and

an adding step, of adding a predetermined mark to data to be printed in said recording step,

wherein the mark added in said adding step is for discriminating the data received in said first receiving step from the data received in said second receiving step when both sets of data are printed in said printing step, and a time of reception, of when the data was received in said second receiving step, is added in said adding step and a time of printing of when the data received in said second receiving step is printed in said recording step, the time of reception and printing also being for discriminating the data received in said first receiving step from the data received in said second receiving step, and these times of reception and printing being together printed on the same face of a recording sheet.
