Print Escape Character for printer Barcode in .NET

fiuhh, this case is one of the most annoying 'simple' approach

requirement is to send 'barcode' to printer directly, because often we using Image print (creating image on the fly then send it to barcode printer)..this one althought works but often the image become blur / discarded

so we need to 'communicate' to barcode printer using its 'language'
the 'language' depends on the printer itself..in my case, we using SATO barcode printer so the 'language' is
SBPL (visit the link for more info)

first we need to design the label
we can use SBPL and design it 'on the fly' make us a little bit crazy

or we can use SATO LABEL Gallery Free to do the job and generate SBPL equivalent for us so we can use it in our code

after we design it, we use "Print to file" method for the printer then print it so we can see what its send to the printer

the generated SBPL will contain 'unseen' character in visual studio IDE (i'm using VS 2010) so be careful with it, u must open it using 3rd party like Notepad++

just replace the 'dynamic' content (ie: productCode, productName, etc) then start printing it

caution:
1. if u need to add , just for readiness of the code then u need to replace it from the SBPL using notepad++ then paste it in code 
before printing don't forget to Replace it again to so it can recognized using this method:

.Replace("", ((char)02).ToString());
.Replace("", ((char)03).ToString());
.Replace("", ((char)27).ToString());

2. don't forget to copy it "as is" from generated File in, must include [STX][ETX] thing

become

and using step 1. to replace it (tooks 2 days to realize it and search for the .NET equivalent way) :(

PS: stilll not sure how to display the Escape Character inside VS IDE ( maybe u'll see 'bad thing inside' :D )

until then
