- the position can be detected.
- the position of the medium on the vacuum table can be detected by reading the barcode formed on each jig. Based on the detected position information, the medium position in the vacuum table can be detected.
- holding table information for specifying the type of jig is described as a character string in each jig, for example, and the operator recognizes the character string.
- a configuration in which manual input to the printer is possible is also possible.
- the position information necessary for printing on the medium by sucking and holding the jig holding the medium on the vacuum table 13 is large. There are two. That is, the position information of the jig in the vacuum table 13 (support position information in the claims) and the position information of the medium in the jig. When these two pieces of position information are detected, the position information of the medium in the vacuum table 13 can be detected based on these pieces of position information.
- USB for example, USB, RS-232C (Recommended standard-232c), wired and wireless LAN, infrared communication, Bluetooth (registered trademark), or the like is used as an interface for connecting the controller 22 and the host computer. It is possible. Similarly, the above-described interface can be used for the interface connecting the controller 22 (host computer) and each reader.
