Wireless board for Samsung M2020

Most likely no - the firmware has to be coded to enable it in the manufacturing mode. These ML models aren't nice enough to have an onboard mode for this, so you need the Samsung software.

The HP M2X and M110 are descendants of the M2020. Please do not buy either; they are infested with HP Dynamic Security firmware and have no real benefits being a cheap Samsung engine. The Samsung ML- units had some DRM but HP dialed it up to 11 :-(. Brother's 12- 15k page drums need constant replacement, but they're far more tolerable than whatever HP has to offer at that price tier.

I did look into it and these lack an Ethernet port like a lot of the cheap Brother and HP lasers, so there's no way to work around it that way. The only thing I can think of that may work is something like a USB print server but a lot of them are not good - you want one from the manufacturer if they made one like HP has the JetDirect server for the stripped printers but even if Samsung sold them at one point, they aren't being made anymore so that forces you to use a 3rd party one. You want one that gives the printer an IP address, NOTHING MORE, NOTHING LESS. You will need to find the address manually from your router or a tool like Advanced IP scanner (Windows) or Angry IP Scanner (Mac, PC, Linux) to find it. Once you do that, you will have to set up the printer and select the drivers manually.

That said, my opinion is your money will be better spent on a modern laser from Brother like the MFC-L2900/HL2460DW. You could also look into a Canon like the LBP172dw/MF465dw. The big thing is check for a Ethernet port out of the box without having to play these games, but that's just me. I run used commercial machines for the sheer value you get since I can maintain them but a Brother HL or Canon ImageClass with a decently large toner will serve you well. I say this because HP isn't going to keep the supplies around forever and will eventually drop the cartridges for legacy engines they did not run themselves with the buyout like they did for the CLP-300, 315 and even some high end enterprise models. HP went out of their way to end these printers short of a lucky few which use similar supplies to the current Samsung engine derived models :-(. Yours may not have survived, but there's a CHANCE given HP did run this engine in the M110. If you buy a new one, just check for an Ethernet port to avoid this same issue. A lot of them got axed right after the acquisition as it stands. -- 515 to be exact.
