An image is created and stored in the image memory 33, or the image stored in the image memory 33 is displayed on the monitor 36 via the display driver 35. When the operator sees the display on the monitor 36 and confirms the image and inputs a print command from the input device 31, the CPU 32 causes a code data command (control code) such as a character code for printing, image data, mechanism control code, etc., via the transmission unit 37. Code) to the outside.

[0006] In FIG. 6, the recording apparatus uses the code data command received from the host apparatus via the receiving unit 11 as a CP.
U12 analyzes and develops into a dot matrix image by referring to the character memory 13 (code image conversion 14) and stores it in the image memory 15. Print driver 17
Drives the printer 18 to cause the printer 18 to print the contents of the image memory 15.

The host device converts the data input by software into a code such as a character code, image data, mechanism control code or the like suitable for the command mode of the set recording device, and sends it. At this time, an error in the setting of use of the recording device on the software, a difference between the resolution of the monitor and the resolution of the printer, the print image assumed by the operator due to the monitor display when using software other than WYSWYG, and the actual printing by the recording device Difference from the image occurs.

[0006]

In this conventional recording apparatus, if there is a mistake in selecting a command mode to be sent to the recording apparatus by software, the upper apparatus is affected by the difference in the monitor resolution of the upper apparatus and the resolution of the recording apparatus. If the image displayed on the monitor is different from the image printed by the recording device, W
When using software other than YSWYG, in order to obtain the print image as expected when the print image assumed on the monitor of the host device differs from the actual print image, it is necessary to print again on the recording device. In this case, the recording medium, the ink, the toner, the ribbon, the energy for printing and the like are wasted, and the time for printing is wasted.

Japanese Patent Laid-Open No. 62-154959 discloses a small reader / printer device for displaying an image which is exactly the same as the image actually printed on a monitor provided in itself, prior to printing. According to the method, the printed image can be accurately confirmed before printing, and waste due to unexpected printing can be prevented. However, this small reader / printer device prints a printed matter or the like as it is without converting the input data taken in from the scanner unit, and analyzes the control code from the host device to develop an image by a dot matrix. Cannot be printed.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a recording apparatus for analyzing a control code sent from a higher-level device, developing the image into a dot matrix image and printing the image on the recording medium, before printing on the recording medium. A display unit for displaying the same image as that to be printed is provided, and the image is printed when the operator performs a confirmation operation after the display of this display unit, and the image is printed when the operator performs an erasing operation. The feature is to cancel things.
