Printer grey scale/bw option is not available

[Fazil]

I was using 22.04 LTS until last week(8 Dec 2023). I upgraded to 23.10 and noticed a difference with the printing options.

In 22.04 (as far as I remember),
There was Monochrome, Grey scale and Color. I used to print using grey scale and it used to print in grey scale.

After upgrade to 23.10,
There is no grey scale option. Instead there is Color, Auto Monochrome, Monochrome and process Monochrome. I tried all the monochrome options and all of them printed with color. Even when I checked preview it was showing color with these options selected. I think the monochrome options are not selected at all.

I too wanted to mention the package. Issue is it is the common print dialog. When I used ubuntu-bug -w option it just showed evince. I downloaded the source of evince to find how the common print dialog is evoked. I will update it once I find it.

So far I found win.print invoked in evince.

Thank you for your bug report. Do you get the same issue in other applications as well? (the text editor or firefox for example)?

Could you provide details on the type of printer you are using and how it's connected to the computer?

[Fazil (fazillatheef)]

I don't know a way to print color using default Ubuntu text editor. I don't think it is possible.

But using LibreOffice Writer from LibreOffice Community 7.6.4.1 (X86_64) got the same result. Also same with Firefox 121.0 (64 bit)

The printer model is HP DeskJet 2632 and Laptop is HP Pavillion 14-BK003

I have connected it using Wifi Direct when I need to print.

@Till, do you have any idea how to debug this issue? How is the GTK print dialog getting the color modes available?
