Hello SeydX,
can you tell me for which printers the plugin should work all ? For all AirPlay printers or only HP ?

I tried it with a Lexmark C3224dw. For this I have entered the IP address in Config but after adding to HK is only the bridge from the plugin is displayed no switch or sensor.

If you have a tip would be cool?

Greetings Nastra

Hi,
I tried to follow your description with the app to get the correct ipp address and I filled in all the necessary data.
Log File says: PrinterPlatformFEHLERCanon MX920 series Sensor: An error occured during getting state
13.2.2022, 14:38:59 HOOBSPrinter Platform FEHLER Received unexpected response status 400 from the printer.
ipp adress is: http://219E74000000.local./mainmenu.html
which I can access with the browser.
Would be really great if you could help me with that.
regards Praktiker.

Thanks for the plugin !

I have installed a Canon G6040 via ethernet and my configuration is as follows:
"name": "PrinterPlatform",
"debug": true,
"printer": [
{
"name": "Printer",
"address": "http://192.168.1.247.local:631/ipp/printer",
"polling": 10,
"marker": false,
"switchType": "SWITCH",
"manufacturer": "Canon",
"model": "G6040",

I can use the AirPrint function of the printer with no problem from various devices.

The Discovery application shows for IPP, adminurl=000000779FE8.local/index.html?page=PAGE_AAP
But trying with http://000000779FE8.local:631/ipp/printer produced errors.
I also disabled the Marker because I was getting errors and Homebridge loads with no red errors,

After reading other resolved issues I also tried http://192.168.1.247.local:631/ipp/printer
I also get no error messages in Homebridge with this address but the plugin does not trigger either the switch or the sensor.

Homebridge is reporting at startup:
Printer Sensor: Configuring accessory...
Printer Switch: Configuring accessory..

so it seems it will work but it doesn;t, after a while:
"Printer Sensor: Can not reach printer!"

Have I got the IPP address wrong?

The contact sensor is always closed and the switch is always off in the home app. They're both unresponsive.

Hi everyone,
Today Homebridge 1.3.0 was released, and since the update, homebridge-printer write every 10 seconds in the logs: [2/20/2021, 5:57:30 PM] [homebridge-printer] This plugin generated a warning from the characteristic 'Filter Life Level': characteristic was supplied illegal value: number -2 exceeded minimum of 0. See https://git.io/JtMGR for more info. without being in debug mode.

Does anyone have this problem? In Apple Home app, everything works perfectly, including the contact sensor when the printer is printing or the switch on/off.

Sincerely,
Victor

}
]

try as well with ipp instead of http and with lower and larger polling time No changes

mabe it is important i use Hoobs

Hi @seydx

Please can you help me?

So here is my config file - when I click Save in Hoobs it returns to the config page and its blank with only []
Its as if it isn’t saving correctly.

Do you have any advice? Is it because the IPP is incorrect - I followed the previous thread saying it should be after the Admin= bit.

Thanks

Hi,
i am using this plugin successfully with an HP printer that it Airprint capablable on its own. Working great!
I now wanted to also add an USB-Printer that is attached and shared in the network from my Mac Mini. I get the following error with this printer:

[14/01/2021, 13:31:38] [PrinterPlatform] Dymo LabelWriter 450: An error occured during getting state

at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:706:12) {

}

Is there a way to allow the plugin to accept self signed certs?

Contact sensor not working for me. I've read your Pull Request regarding this but not 100% what I need to do and how. Some tips would be really good on how I get this part working. Thanks

I'm receiving this message, around one every second, since last update:

Any Idea ?

Hi SeydX,

I installed a new Epson ET-2756 printer in homebridge-print and got following error-message:

Corresponding config enrty is:

            {
                "name": "Epson ET-2756",
                "address": "http://epson-et-2756:631/ipp/print",

                "serialNumber": "123"
            }

If I use IP number instead of DNS name I got the same. With marker = false I gott also this error, but without details error message first time after restarting hombridge.

Maybe helpful additional information from Discovery app on my iPhone:
mopria-certified = 1.3
rp = ipp/print
TLS = 1.2
txtvers = 1
ty = EPSON ET-2750 Series

Thanks in advance.

hi i can find printer IP address but d not know anything about ipp

how to find it pls?

Hi,
I installed plugin, logs are showing successful communication with printer.

This is config:

"polling": 10,
"marker": false,
"switchType": "SWITCH",
"manufacturer": "HP",
"model": "DeskJet 2676",
}

But sensor shows as closed. No more information.

Same thing in Apple HomeApp.

Is it expected behaviour?

When the printer is off, homebridge/homekit shows that the printer is on and I get this error message:

}

}

Is there any possibility to solve it and show the correct status in homebridge/homekit?

config:

{
    "name": "PrinterPlatform",

    "printer": [
        {

}

Thanks in advance.

Hi,
I Ihave HP Airprint supported printer. But I don't get printing status as mentioned in description.

Does it require separate ContactSensor accessory to show printer is printing? If yes then which contact sensor is required?

Not able to identify config for switch and contact sensor accessory in plugin. sorry for basic question but I am new to this setup.

Hello @seydx,

would it be possible to optionally display the printer as one device under the contact sensor?

Now that I discovered you have a bunch of other awesome homebridge plugins, I installed this one but am facing an issue with I think the ipp address.

Using the Discovery iOS app, I could get details of the printer, I tried with adminurl = http://B06F18000000.local./mainmenu.html, also http://b06f18000000.local & http://b06f18000000.local:631

Any ideas? The links above are accessible via a browser, I land on an AirPrint settings webpage.
Thanks

EDIT: out of curiosity, I tried changing b06f18000000.local to the actual IP address, then the message is different:

Hello,

I have a trouble with SWITCH. I tried address from DNS checker like http://NPI029ABF.local./hp/device/info_config_AirPrint.html?tab=Networking&menu=AirPrintStatus but it not reacheble .. work only

Hi @seydx, the switch does not seem to function based on online/offline state, whereas the contact sensor works perfectly.

I have a Canon MG4250 and the switch does not turn on when the printer is online. The contact sensor accessory correctly changes state when the printer is printing, and changes back when done printing, but the switch accessory never changes.

Thanks in advance for looking into this

When I Add my HP Laserjet everything works fine but I get these Error in the Log. My Printer is behind a CUPS server.
Seems something is wrong about the markers

[PrinterPlatform] TypeError: markers.forEach is not a function
    at SwitchAccessory.getService (/root/.hoobs/node_modules/homebridge-printer/src/accessories/switch.js:50:21)
    at processTicksAndRejections (internal/process/task_queues.js:93:5)

The Debug Log of the Plugin is as follows

[PrinterPlatform] HP LaserJet: {"version":"2.0","statusCode":"successful-ok","id":3177504,"operation-attributes-tag":{"attributes-charset":"utf-8","attributes-natural-language":"en-us"},"printer-attributes-tag":{"printer-is-accepting-jobs":true,"printer-state":"idle","printer-up-time":1611551364,"queued-job-count":0,"marker-levels":63,"marker-names":"Patrone Schwarz HP CE505A","printer-make-and-model":"HP LaserJet P2055 Postscript (recommended)"}}

so the log seems to have information for markers and marker-level (despite the printer it self says 58% marker) but that might be some CUPS issue
