I never managed to make this work connected directly to the printer SSID, even with your fix.

Instead, I had to physically connect the printer first with a USB cable (connected to the computer) then through ethernet (RJ45 cable connected to the router), to be able to finally activate Wi-Fi.

HOW TO:

1. Power the Slash on. Connect the printer to your computer with a USB cable. Open latest Uniz desktop app. Make sure your computer is connected to the Internet.
2. As the USB cable is connected, the printer is now visible in Uniz app. Clicking on the gears icon, activate the printer if this has not been done yet. Restart the printer. After that, remember to select a Plus model in the drop-down menu if you have an OL printer during the 7-day trial period, or your temporarily upgraded printer will not be visible again in the app after reboot!
3. Connect the printer to your router with a RJ45 cable. Click on the gears icon again, you should see if ethernet is working. On mine, weird thing again: ethernet was indeed detected, but no dynamic IP address could be given to the printer. I chose to select a static IP address instead (you need to choose a valid IP address on your LAN, provide the correct subnet mask, router IP address, and DNS). It worked.
4. Type this newly chosen static IP address (instead of 192.168.12.1) in your web browser. The same printer internal web page should pop up.
5. Click on the “Check Network” button: a message should tell you the printer is now connected to the Internet (it’s indeed connected with the ethernet cable).
6. Select your home SSID and type your WPA/WPA2 password. Click on the “Connect” button and wait for 20-25 seconds (this is important, there is no visual feedback from the button, nor anything else in the page, but it works). Alternatively, instead of clicking on the blue “Connect” button, press the Return key on your keyboard, while the password field is still selected with the blinking insertion point within.
7. The printer is now connected wirelessly to your home network.

I had to do that in that order: USB, ethernet, Wi-Fi, to make Wi-Fi work. This is not explained in Uniz docs.

i have the same prolem, i am activating uniz slash plus, and when i am at webpage 192.168.12.1 the printer is not appearing on the list…

I have the same problem, printer will:

1)turn on,

2) I can see it connecting to the app(on phone),

3) activated my printer/licence for udp over phone app via slash wifi,

4) phone app says it is connected,

5) downloaded new firmware.

6) usb cord is connected from cpu and printer.

When i go to just turn on the screen(just to test) it turns off within a second. No “pop up” window saying what may be the problem. When this happens printer(front light) turns from solid green to red and will no longer communicate with app. I need to restart(power off then power back on) the printer to get it to connect again. If i import a model on desktop app, it asks me to select a printer. I select the printer version that is showing up on my (phone) app but no success. what am i missing?

Sent Uniz many emails and they sent me the same information over and over again but don’t actually answer my questions. so many weeks have passed that i have lost my UDP trial with them for the UDP printing capabilities (and basically the bottle of resin that was included with the kit) and they will not give me any days back. Uniz is delayed with emails. returning an email more then a week later to which i sent 5 emails; unless i email the same email to as many Uniz employees as possible(min 5), then it is only 2-3 days. i didn’t know time zones are a 3 days or a week long/different (sarcasm) !!!

all this sums up into one question that Uniz can’t answer (they try but don’t show anything but what is on their website)

I have sent them the same information via many mediums, text, pictures/screenshots, i’ve asked for them to call me and gave them my phone number and told the to call anytime. never called.

how do i connect my printer, when all the above is already complete?

can someone point me in the correct direction. or should i start a new thread? 

Thanks in advance

There is even nothing to supplement here, original essay because you have offered the most complete instruction on solving problems that could lead to such failures.
