Stream PCL from VC++ 6.0 COM dll to ActiveX Control to Printer

Stream PCL from VC++ 6.0 COM dll to ActiveX Control to Printer

Stream PCL from VC++ 6.0 COM dll to ActiveX Control to Printer

(OP)
I've written a VC++ 6.0 COM dll that we use for printing MICR lines on checks.  This dll has been used very successfully to print check data, a signature and a MICR line to a HP printer using PCL.  It sends the PCL codes directly to the printer which produces great results.
  My problem is getting this data to go from the COM dll, with the limited COM interface data types, to a .NET Web Service, then to a .NET ActiveX Control that streams the data to the printer.
  I seem to lose the Binary properties of my PCL MICR line and signature along the way.  I have a PCL reader that tells me my MICR line and signature should be in the same binary format acceptable by the printer but I've yet to get this to work.
  My problem/question is has anyone ever done this and if so do you have any suggestions for returning the PCL Stream from the VC++ 6.0 dll?  I think this is where the data format is getting changed from binary to a string.
