The task I have is pretty basic: Generate a PDF label with some barcodes. To get there is a bit of a mission though, mostly due to the availability (or lack of) tools.

I create an html template and have wkhtmltopdf convert it to pdf. Easy enough, but having precise layout and positioning in html isn't always that easy.

Generating code39 and 128 barcodes is relatively easy with JsBarcode. Except when it doesn't want to display once converted to pdf. Then you find out you have to set both the script and html to utf-8 encoding and then it works.

Generating a 2D pdf417 type barcode is relatively easy with a javascript library, except it fails to display once converted to pdf by wkhtmltopdf. So I find a .Net Core library that can generate the barcode as a png, convert the bytes to a base64 image and use that in the html by replacing placeholder text.

Another hurdle was wkhtmltopdf suddenly becoming very slow after being pretty fast in the past. Finally tracked down the issue to spoolsvc and my default printer being a network printer that's not connected anymore. Once removed the conversion works at a decent speed again.

In short, what should be an easy task had lots of complications and workarounds, some quite weird and difficult to track down, but in the end I learned some interesting things Smile | :)
