I am using the NuGet package Rotativa which in trun uses wkhtmltopdf.exe in a MVC 4 web application to generate PDF barcode documents from a standard MVC view.  While QRcode and Code128 barcodes work fine, Code39 and Code93 do not.  

The code to invoke the view is:

return (new Rotativa.ActionAsPdf("PrintTrailerPage", new { id = id, barcodeType = Request.Params["barcodeType"] ?? "qrcode" }) { FileName = String.Format("Trailer Page for {0}.pdf", model.DocumentName, model.BarcodeValue, model.ID), PageSize = Rotativa.Options.Size.Letter, PageOrientation = Rotativa.Options.Orientation.Portrait, PageMargins = { Left = 0, Right = 0, Top = 0, Bottom = 0 } });

Curiously, PrintTrailerPage, which Rotativa invokes, always renders properly when displayed directly in the browser.  Do you have any ideas or insight that might help remedy this issue?

Hi,

I tried converting directly with wkhtmltopdf v. 0.12.1-rc3 and all barcodes are rendered without issue.

Output: see attachment

Rotative seems to be using quite an old version of wkhtmltopdf. Perhaps you can try to update it in place.

I also recommend to switch to SVG rendering since you're outputting in a vector format:

I hope this helps.
