Print barcode in a fiscal printer using POS for .NET

I am working with fiscal printer in POS for .NET.

I need to print a barcode. The only way I found was using the DirectIO method of PoSCommon.

I only can print the barcode 010803111200002801234567890 like:

DirectIO(0, 1075, code)

But I can print for example the barcode %S0003014000097

Also where I can find a good description of what means the parameters of DirectIO, because the official documentation is poor.

I was able to find documentation about how the process of print a bar code works.

In the method DirectIO(0, 1075, code) one can change the values to;

DirectIO(0, 1071, code)

where code must have an specific format, the result string is: OP + TypeBarCode + ValueofBarcode

for example if you have a barcode that is "%S0003014000097", then its format is CODE39(this is an universal format). The format CODE39 has a value type of 4.

Then the final string is "014%S0003014000097" where the first two digits are the operator.
