Web based printing from a Django application?

Question

Is there any recent developments in web based printing?

I know using @media print in CSS, PDF based solution or iTextSharp but they are not really easy (except @media print) but alignment is little tricky if receipt contains barcodes or if I have to format for A5 etc.,

Is there anything new in HTML5 which will support this?

I would like to print receipts from a Django based webapplication.

Any tips?

Thanks.
