I am back to using Lubuntu after a long time, very excited to use / explore the lxqt DE, big congratulations and thanks for the fantastic efforts of the whole lubuntu community.
I want to define and set a custom paper size for printing. I was able to do this in the print dialogue in the linux mint (my previous desktop). In lubuntu I am able to use custom size to change the size of paper before printing in the print dialogue, but how to define a custom paper size with a name and set it as default. This option will be very useful to me, so any help appreciated. Thanks.
