We're developing a browser-based warehouse app that needs to print labels and invoices regularly. We want to be able to print to the local printer without clicking through the the usual browser print dialogs. Is this possible? Possibly using a greasemonkey userscript? We don't want to have to setup a whole CUPS printer network and deal with all that, but warehouse pickers having to click through a print dialog 1000 times a day isn't an option.
We're printing PDFs, not sure if that matters. If we could do this another way using HTML5 or something else I'm open to course changes or other ideas here.
