Steps to reproduce:

Trying to print invoices on POS printer, as usual. (Made with an online billing system.)

Actual results:

The POS printer is printing 1600 mm long empty paper before the invoice.

Because a POS printer's default paper size is : 72mm x 3200mm (dynamically auto-cuts at the doc end).

Hundreds of meters of paper wasted since Firefox update ca. 6 weeks ago at all places everywhere in the country. (And maybe other countries too).

That's why users are currently forced to change to Chrome Brower.

Expected results:

Start printing at the TOP of the page, like it was before.
DO NOT VERTICALLY CENTER !!!

If you want to introduce new "features" at least put next time a switch on the print-preview page:
Vertical center: [ OFF default ] ... On

The Bugbug bot thinks this bug should belong to the 'Core::Printing: Setup' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

jwatt, I know you've been monitoring receipt/thermal-printer bugs -- do you know if this one is already known?

(If we're lucky: maybe it's even already fixed, if this already happened to be tracked in a duplicate bug? I don't know how to test this locally, not having one of these printers myself, so I'm not sure if it's still an issue.)
