Description Dr. Martinus 2022-05-22 09:19:34 UTC
Description:
I'm sorry I couldn't find a short sentence that describes the problem. I want to print a 2-page document multiple times. I set in the print dialog let's say 50 copies. Below is a check box named "sorted" or similar (I have it in German), which is enabled. The corresponding images show "1,2,3 - 1,2,3" pages, so I assume, that each copy is printed with page 1 on the front page and page 2 on the back page. If I uncheck the "sorted" box, it shows "1,1,1 - 2,2,2" which lets me assume that then first it will print all first pages (50 times, duplex, so you have 25 papers whith page 1 on both sides and 25 pages with page 2 on both sides). I understand that this may be useful when printing one-sided, but it makes no sense to me when it's duplex printed. 
What happens is: when I have the check-box for sorted printing checked, I get what is shown by the small images when sorted is unchecked, so it prints 25 papers with page one on both sides and 25 with page 2 on both sides. This is stupid and cost me already a lot of paper and ink (=money). 
Even if I just misinterpret the images next to the sorted check-box (which I don't think I do), it is wrong to have this as the default setting. When I want to print duplex, I naturally want to have page 1 and 2 on one sheet, and not two sheets whith each the same page on either side.
Note that this happens only when printing multiple copies, which is natural.
One more thing: I tried printing with "sorted" unchecked, I got the same result. When checking it again, it worked correctly. It seems to be important to have also "print individual print jobs" checked, but this doesn't have an effect the first time...

Steps to Reproduce:
1. take a multi-page document
2. print multiple copies of the document with a duplex printer as duplex printing 
3. keep the "sorting" check-box checked

Actual Results:
You get multiple papers with page one on both sides, later multiple papers with page two on both sides

Expected Results:
You get multiple papers with page one on the one side and page two on the other side...

Comment 1 Dr. Martinus 2022-10-14 07:35:44 UTC
I am now at version 7.6.3 of LO under Manjaro, and the problem has gone away. While the people at Manjaro said that this problem must be caused by some error in my setup (an almost fresh installation), it disappeared after some updates to the package, so I am pretty sure it was caused by some adjustments made by Manjaro. Maybe I was the only one suffering from this problem, but maybe just because I was the only person doing duplex printing on an regular basis with this setup. Whatever, it works now with LO 7.6.3.

Sorry,  I forgot to mention, that this may have been a bug in CUPS and not at all related to LO. But i never figured out how to solve it, until the upgrade solved it.
