(Second embodiment)
[0019]
In the printing apparatus of the first embodiment, the communication time is determined not only from the type of IC chip mounted on the RF-ID tag but also from the amount of data actually recorded in the RF-ID tag. Thus, the present invention can be implemented.
[0020]

From the set communicable range or the allowable communication range and the communication time, the sheet conveyance speed is determined using Expression 803 (step 1206).
[0021]
(Third embodiment)
In the printing apparatus according to the first embodiment, the label is transported before printing of the RF-ID tag, and the communicable range and communication time are measured by actually communicating with the RF-ID tag. The present invention can be implemented by calculating the sheet conveyance speed.
[0022]
A method for determining the conveyance speed of the printing apparatus (100) used in this embodiment will be described with reference to FIGS.
In order to measure the communicable range, the printing apparatus (100) transports paper on a trial basis and performs dummy communication at equal distance intervals. The dummy communication starts from outside the communication range with the RF-ID tag (1301) (step 1401), and determines the communicable range with the RF-ID tag (1402).
If communication is not possible, transport is performed to the next dummy communication position, and dummy communication is performed again. When the communication is successful (1302), the RF-ID communication start position is determined with reference to the position, recorded in the RAM (310R) (step 1403), and the RF recorded in the RAM (310R) at the communication successful position. -Write the ID write data to the RF-ID tag and measure the communication time (step 1404).
Dummy communication is started again to determine whether communication with the RF-ID tag is possible (1405). If the communication is successful, transport is performed to the next dummy communication position, and dummy communication is performed again. If communication is impossible (1303), dummy communication is terminated (step 1406), and the successful communication position before communication is disabled is recorded in the RAM (310R) as RF-ID communication completion (step 1407).
The communication range is calculated from the RF-ID communication start position and the RF-ID communication end position recorded in the RAM (310R) using the formula 1404, and the communication range is compared with the conveyance direction size of the continuous label paper (step) 1203). If the communication range exceeds the continuous label sheet conveyance direction size as shown in FIG. 6A, the communication range is set to the continuous label sheet conveyance direction size (step 1409).
From the communication range and the communication time, the conveyance speed is determined using Expression 803 (step 1410).
When the conveyance speed is determined, the label sheet is returned to the print start position (step 1411).
Although the present embodiment has been described with respect to a full-line type ink jet recording apparatus, it is also effective in a serial type printer that scans the recording head perpendicular to the paper conveyance direction, and the gradation of the recorded image. This is also effective for printers having a recording head other than the ink-jet method, to which a light-color ink recording head is added in order to improve the performance.
[0023]
【The invention's effect】
As described above, according to the present invention, the optimum conveyance speed is set according to the difference in the size of the paper medium, the type of IC chip used for the RF-ID tag, the size of the RF-ID tag, the writing capacity for the IC chip, and the like. Therefore, it is not necessary to stop the conveyance when writing the RF-ID tag, and it is possible to prevent a decrease in printing speed inherent in the printing apparatus.
