we have a big problem with additional barcode for shipping labels in our invoices.
We started our planetpress-project wednesday last week, with no problems, and since yesterday especialy the external barcode disapears on each invoice which includes the external barcode.
The configuration of the external barcode is correct, and when I print a single invoice the barcode is also correct. When much invoices are running (about 50 in 10 minutes), we see that the external barcode is missing. All other barcodes are printed correctly.
I am sure that the designer template, the mapping, and the output-preset are correct.
Where should we start to solve this problem, because it is very urgend.
