Which I literally agreed with? So what’s the point of showing me the info I already know?
As I said above:
I understand that, I am responding to the statement that no USB means no LAN. This id the H2D
Wi-Fi Transmitter Power (EIRP)
2.4 GHz: <23 dBm (FCC); <20 dBm (CE/SRRC/MIC)
5 GHz Band1/2: <23 dBm (FCC/CE/SRRC/MIC)
5 GHz Band3: <30 dBm (CE); <24 dBm (FCC)
5 GHz Band4: <23 dBm (FCC/SRRC); <14 dBm (CE)
Wi-Fi Protocol IEEE 802.11 a/b/g/n

No USB means no LAN printing on the H2D. This was part of the leaked FAQ in the following post:
Not sure what the wifi specs have to do with their software restrictions/hardware limitations
I see that they are using USB to indicate external card/storage slot.
I also find these 2 statements conficting.
So are they just throwing out fun facts or are they saying the internal storage is USB connected (and potentially moddable) ?
It really seems to me that there is a lot of potential mis-info here. It reads like to see any logs for troubleshooting they will need direct access to the printer and I don’t see that happening outside PRC.

What do you mean? You would enable logging, do a print or whatever, then take the USB out of the printer and over to your computer and pull the logs from it. What is conflicting there? You need a USB drive made within the last 25 years and the printer can only accept a single drive. It’s pretty clear to me.
If you’re talking about “Log files cannot be exported.”, that is the function that is not operational without a USB, as we do not have access to the internal storage

It sounds like the USB is just replacing the existing function of an SD card.
And I guess the “no printing via LAN” means no LAN mode. Not shocked at all though. This thing is basically a downgrade as far as connectivity options. So this is probably what they want to do with their existing lineup - revoke LAN mode entirely.
^ WRONG ! ^
Why you would want to be obligated to provide and pay for a free cloud service, I have no idea. What kind of business throws away money like that?

I really do not understand how people are getting that from reading this. It’s very clear that those features are disabled UNLESS you insert a USB drive into that printer so it has the extra storage.
If you want to use LAN mode, dig through your desk drawer, find that old flash drive you still have from high school for some reason, format it as exFAT, and shove it into the printer’s USB port. Congrats, now you can use LAN mode.
Why is this replacing the tried and true SD card? No idea, doesn’t make sense to me, but it’s pretty clear that the listed features are only unavailable if a USB drive is not inserted in the machine
I don’t think you mean what you just said or perhaps you haven’t experience LAN mode. LAN mode is direct transmission over Ethernet the GCode files right into the printer’s SD card and then sending commands over the same network directly to the controller to commence print. What you describing with copying onto USB and walking the files over to the printer is at best slang for “Sneaker Net”.

Yes, I am aware. But it seems this time instead of an SD card, it’ll be sent to the USB drive. I’m not suggesting you walk the USB drive over with the gcode on it, I’m saying that the USB is the new SD card on this printer. You plug it in and forget about it and use LAN mode like you would normally until it gets full and probably alerts you on the screen.
The only time you’d need to remove it is if you need logs or need to free up space
For clarification:
THERE IS NO SD CARD SLOT ON THIS PRINTER. ONLY A USB PORT

Oh I think I see what you’re saying, yes you’re probably correct. It guess it works the same way as the existing things, but a USB stick replaces the SD card. This is what happens when I skip the post-work nap.

I get you lol, honestly I would prefer an SD card so it sits flush with the printer. I don’t want a big 2 inch USB stick sticking out the back of the printer, it’s liable to get damaged if I accidentally bump the table and it hits the wall
Maybe it’s recessed somehow…
Maybe it’s well enough designed that it’s out of the way.
Then again maybe it’s designed by the designer of the new auth system.

This is the part I had missed, which was why I was trying to make sense of the conversation: “and USB Port”
| Electronics | Touchscreen | 5-inch 720*1280 Touchscreen |
|---|---|---|
| Storage | Built-in 8 GB EMMC and USB Port | |
| Control Interface | Touchscreen, mobile App, PC App | |
| Motion Controller | Dual-core Cortex-M4 and Single-core Cortex-M7 | |
| Application Processor | Quad-core 1.5 GHz ARM A7 | |
| Neural Processing Unit | 2 TOPS |
OK. So maybe it is listed in one of the leaked specs that I missed. Let me expand upon some items related to a USB “port” to make sure I understand what we are discussing.
When referring to the USB port what is the device “class” as defined by the USB Implementers Forum (USB-IF)? USB Device Classes - Developer Help
Here are some examples of what I mean.
- HID (Human Interface Device) Class (0x03) – Covers devices like keyboards, mice, game controllers, and other input devices.
- Mass Storage Class (MSC) (0x08) – Covers USB flash drives, external hard drives, and other storage devices.
- Printer Class (0x07) – Covers USB-connected printers.
- Still Image Class (0x06) – Covers scanners and digital cameras that transfer images over USB.
If the port is a Class 0x07, then the OS will treat it as an output printer. If it’s a 0x06, it’s treated like and input imaging device and of course a 0x03 is a HID device like mouse, keyboards etc. Which Class is the H2D USB Port?
Details matter.
Dude seriously, take a moment and think about this. The FAQ says you need a USB drive in the printer for LAN mode. Does it really matter how they configure that as long as you can access the files and it works on the printer? You are digging for reasons to be unreasonable when the FAQ is very clear. The USB is a key for LAN mode, doesn’t matter how they end up using it, you need a USB drive in the printer for LAN mode. LAN mode exists and is usable, you just need to format and plug a USB drive into the printer. I don’t know how else to say this, so I’m no longer going to reply to you in regards to this topic, as I genuinely believe you are deliberately being difficult.

I think you’re reading too much into it - according to rumors, the USB port is not mentioned as a connectivity option, and the omission of an SD card slot only implies that it will have an USB port (like the existing P1/X1 ones) which you can use to add storage to the printer.
And in that way - it would act as the existing printers, you won’t be able to use LAN-only mode without some storage available to the printer as there is not enough operating buffer to store large G-code files (or to store print logs / recordings) locally. Sure, they can implement trickle-deployment locally as well, but they don’t want to be bothered at this time apparently. That being said, if they’re not investing in local deployment without storage their decision to further lock down their printers and funnel all comms through their authorized middleware makes even less sense…

now, can we just run a usb cable from our pc to the printer? Would that be even smarter than ethernet? Since not all motherboard have an output. And most people just have a single router in their home? no network needed. Print without a router involved?
Ethernet makes since in a farm setting, but does anybody think these will end up in farms? Or sitting next to a pc?
In the specs list it only mentions USB under storage, I may be reading into though. I don’t see another category it would fit under unless you think “network control” fits but I wouldn’t think so.
I don’t personally foresee these in farms, maybe one for specialty prints, but otherwise I feel like there are many printers with a better value for your main fleet

Just to be clear, in case you haven’t realised it by now, from how the leaked specs describe this, it will not be a USB client port (ie. HID, MSC, etc) but a USB host port, for a USB flash drive to be connect to it.
And from this, the USB flash drive needs to be present in order for you to send a print over WiFi using LAN mode.
