#Artix #Linux #CUPS #problem with #Brother #Laser #Printer #LAN connection.

I have Brother HL-4150CDN laser printer connected over Ethernet to my home router (TCL LinkHUB HH130VM).
CUPS properly detected the printer and added it with the driver I got from the internet.
Now, when I send a job, the printer status very quickly changes from "Idle" to "Cannot locate printer".

Printer description says:
Driver: Brother HL-4150CDN series CUPS (color)
Connection: lpd://BRN001BA9A97CA4/BINARY_P1

I do not even know where to start solving it...
Will do some search, but perhaps someone here knows the solution already?

Obvious question — what do CUPS logs say (if nothing, ask the daemon for some more verbosity: https://wiki.debian.org/CUPSDebugging#The_CUPS_Error_Log)?

And a blind shot: has the printer static or dynamic IP? Maybe the discovery part was done just once, at install, and since then printer's addres has changed?

Hm, two things that stick out are ippfind failing (probably unrelated, but...) and these two lines:

W [28/Sep/2023:21:49:49 +0200] [Job 162] Grayscale/monochrome printing requested for this job but Poppler is not able to convert to grayscale/monochrome PostScript.

W [28/Sep/2023:21:49:49 +0200] [Job 162] Use \"pdftops-renderer\" option (see cups-filters README file) to use Ghostscript or MuPDF for the PDF -> PostScript conversion.


Have you tried the suggestion? “Poppler is not able to convert to grayscale/monochrome” is obvious bullshit, but maybe circumventing the failing path would help. Check https://github.com/OpenPrinting/cups-filters/blob/master/README.md#postscript-printing-renderer-and-resolution-selection for possible options.

Also, some older Brother drivers had an unfortunate habit of bringing 32-bit binaries even in 64-bit systems; check the drivers, esp. brlpdwrapperhl4150cdn. In such cases, usually adding 32-bit libc to system was enough.

I forgot to add that when I connect it via USB, it works without any problem.
That makes me think it is the network layer issue.
I will see that 32/64 bit later - multitasking now.
