Please, could you share the full ZPL code that you are using. The ZPL for a 2 x 1 tag, should be adjusted for 1 x 1/2 tag dimensions. Not only RFID calibration is required, it is also recommended to do a label calibration , and review if the label area for the small tag is covered in the label for ZPL printing commands correctly. Also, could you share the "allcv" report of the printer, so we can review if there are settings of the printer that need to be adjusted as well. Otherwise, the best channel to work this type of issues should be through our Technical Support team, you can request to open a ticket.
Thank you for your reply. I both performed both label and rfid calibration each time I switched sizes. I used the same ZPL for both sizes - the small tags is printed correctly, the larger tag simply gets the printing in the upper left quadrant. The larger tags get the expected printing and the epcs are correctly encoded.
I know how to get the "Printer and Network Configuration Reports", but cannot find anything in the user guide as to what the "allcv" report is - could you please clarify?
I normally wouldn't use the ^RS8, but was trying to see if it made a difference and it didn't seem to cause any trouble.
