Clean Print Head doesn't apply to the QL driver. "cleaning" the heads requires either a cleaning card or a bit of manual work (can't remember if the 570 is like a Zebra printer; the instructions should be in the manual).
The CUPS test page is geared up for page printers, not label printers. I haven't tried it with the Ptouch driver but I wouldn't be surprised if it had problems. As I said - you need to configure the label dimensions correctly in both the driver and the application. I've never tried Libreoffice, but gLabels works well. If you get the page size wrong (especially width), the printer may refuse to print on the labels. Can you post the settings you have set in the driver? Screenshots from CUPS (http://localhost:631 -> printers -> QL) would be useful, and I can see if you have anything set obviously wrong. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ptouch-driver in Ubuntu. https://bugs.launchpad.net/bugs/1735991 Title: QL-570 printer : the led flashes red and nothing happens Status in ptouch-driver package in Ubuntu: New Bug description: The label printer Brother QL-570 refuses to print ...
