I've managed to source a slightly-used QL-570 for a more reasonable price, along with (apparently) five rolls of labels. That should be arriving "soon-ish".

As I've said on the upstream ticket, the negative-print bug looks like the thing losing track of a buffer and may be tricky to debug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1604036 Title: Upgrade printer-driver-ptouch to support Brother QL-570 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hwdata/+bug/1604036/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
