I have the exact same problem with my Brother QL-570 label printer. I am running Raspbian Jessie and manually installed the binary driver package from the Stretch (v1.4.2-2) repository. This was an attempt to fix a problem with the cutter that was introduced after upgrading from Wheezy (v1.3-4) to Jessie (v1.3-8). However with version 1.4.2-2 my printer stopped working altogether and the red light comes up when attempting to print labels, in my case 62 mm wide continuous roll tape.
I have set up Custom Media Size as 59 x 32 mm (yielding 62 x 38 mm paper size effectively) in CUPS to account for the hardware margins (1.5 x 3 mm). This was working fine in Wheezy when printing custom labels generated with glabels having the same dimensions as the printer media size (59 x 32 mm). I have seen that provided label templates follow the same approach (at least in earlier versions of glabels). As already pointed out in the discussion the reported problem is potentially related to the media size. I have noticed the latest PPD has updated the HWMargins option which may conflict with the Custom Media Size I am using. Can you tell me what setting to use for Custom Media Size in CUPS and the correct dimensions for labels created with glabels. I am aiming at 62 x 38 mm. I can report back if this fixes the problem with the blinking red light. Meanwhile I downgraded to v1.3-4, but I want to see the problem resolved properly. I also managed to compile the drivers from source, so I can try out driver patches if necessary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1735991 Title: QL-570 printer : the led flashes red and nothing happens To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ptouch-driver/+bug/1735991/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
