I've been looking for a cheap b/w laser for my parents and have found HP LaserJet 135/135w. It looked very familiar, and behold, it is a rebranded Samsung SL-M2070w that I have in the office.
Hardware-wise, it is actually a nice printer. Software-wise... It works in Linux, but you have to install the binary-only uld driver. For MacOS it is more interesting: printing is not a problem, scanning in B/w is also OK, but scanning in Image Capture/Preview in color into PDF produces garbage output. What works is scanning in color into TIFF, then stitching and reexporting into PDF manually. The alternative, the EasyScan Samsung software no longer works in Catalina, it has 32-bit components.
Edit: from the ppds in the driver package, they are:
* HP Laser 10x Series
* HP Laser MFP 13x Series
* HP Color Laser 15x Series
* HP Color MFP 17x Series
So weird that HP would buy Samsung's printer division but not kill it off.
... and I believe it. Unless you researched it heavily that was just good luck, honestly. Your printer has a good OSS driver, and it worked. Mine did not, even though I thought Brother was generally OSS-friendly. :(
Well, at least the binary (x32!, if you can believe that) driver basically works, but no duplex... which is sad because I bought said printer because it had the duplex capability :/
This one doesn't appear to have Ethernet.
I have one of their all-in-one office machines. It prints pretty well. The wireless scan is complete garbage. A known issue with their drivers, apparently.
... although I was disappointed recently by my usual go-to of the Brother brand. Their Linux/CUPS drivers are some sort of bizarre concoction of Perl scripts and x32 binaries... and still cannot print in duplex :/.
(I believe the duplex problem is probably a typo somewhere in the PPD or Perl script, but I don't know enough about PPDs and/or Perl scripts to be sure. I do know programming, hence my suspicion.)
Lesson is: Research if the EXACT printer you're purchasing is supported by the usual Gutenprint or whatever.
