Abstract
Writing incorrect information to an IC tag affixed to a label is prevented. When a control command including recording information, an instruction to print the recording information on a label, and an instruction to write data including at least time-related information to an IC tag affixed to the label is received from a host computer, the system controller of a label printer prints the recording information and writes the write data based on time information input from a RTC, but does not print the recording information and write the write data based on the control command if an error was detected by RTC error detector.
Claims15
A label printer configured to connect to a control device, the label printer comprising:
- a real-time clock configured to keep time;
- an error detector configured to detect a real-time clock error;
- a data writer configured to write predetermined information by wireless communication to an IC tag embedded in a label on continuous paper;
- and
- a printing mechanism configured to print on the label;
- and
- a controller configured to
- control the data writer,
- control the printing mechanism,
- check the error detector when identification information is received from the control device,
- acquire time information from the real-time clock,
- cause the data writer to write the time information and identification information to the IC tag and the printing mechanism to print a symbol code on the label if the error detector did not detect a real-time clock error, and
- cause the data writer to prohibit the writing of the time information and identification information to the IC tag if the error detector detected a real-time clock error.
A control method for a label printer configured to connect to a control device and including a real-time clock configured to keep time, an error detector configured to detect a real-time clock error, a data writer configured to write predetermined information by wireless communication to an IC tag embedded in a label on continuous paper, and a printing mechanism configured to print on the label, the control method comprising:
- checking the error detector when identification information is received from the control device;
- acquiring time information from the real-time clock,
- writing the time information and identification information to the IC tag using the data writer and printing a symbol code on the label using the printing mechanism if the error detector did not detect a real-time clock error;
- and
- prohibiting the writing of the time information and identification information to the IC tag if the error detector detected a real-time clock error.
A non-transitory storage medium configured to store a program for execution by a controller configured to control parts of a label printer configured to connect to a control device and that includes a real-time clock configured to keep time, an error detector configured to detect a real-time clock error, a data writer configured to write predetermined information by wireless communication to an IC tag embedded in a label on continuous paper, and a printing mechanism configured to print on the label, the program causing the controller to:
- check the error detector when identification information is received from the control device;
- acquire time information from the real-time clock;
- cause the data writer to write the time information and identification information to the IC tag and the printing mechanism to print a symbol code on the label if the error detector did not detect a real-time clock error;
- and
- cause the data writer to prohibit the writing of the time information and identification information to the IC tag if the error detector detected a real-time clock error.
