No matter what I do, at print time I cannot get the page length for some custom labels to be 12 inches. The overall page of labels is 4.25 by 12.0. 12 labels per page. At print time, Libreoffice selects as its paper size a #10 envelope longways. I can find no way to cause it to use the custom size I have setup when creating the document. I would hope there is a way to create and save custom document sizes.
It should not be this hard. Envelopes and labels have pretty much always been an abomination - for me at least. I’m using Opensuse Leap 15 with Liberoffice Version: 6.0.5.2 Build ID: 00m0(Build:2). Printer is a HP Laserjet Professional P1606dn. I would love some help on this.
