I think this is pending on the used printer driver and its language. Toshiba is using TPCL (Toshiba Print Language Control) which the printer driver needs to support. Each driver has its own “syntax” for writing RFID tags. We are using Zebra driver and the article Printing RFID-Tags With List & Label was a good point for us to start.
But quick search for Toshiba printer drivers revealed that the tags are different - similar structure (without guarantee of completeness and function):
#RFID_START => ^RFR
#RFID_DATA => ^RFV
#RFID_WRITE => ^RFW
#RFID_END => ^RFE
The structure of the text object with this structure should therefore look something like this: "${^RFR;^RFV<YOUDATAINHEXCODE>;^RFW;^RFE}$"
I can’t test it and I don’t know if it’s going in the right direction… but maybe this will help as a start and inspiration. Maybe each command needs a line-break - or not. Also pending on the printer driver.
