Print and Professional Layout Manager has incorrect IP address

[roger_cavanagh]

My P-300 is set for wireless operation on my Mac Studio. I can print to the printer from other apps, but PPLM shows the message printer on standby, and shows the incorrect IP address …138. I can connect to the printer through the remote UI interface on the correct address …114. Everything seems to be okay.

I have restarted the router, the printer and the computer, but PPLM still shows the wrong IP address.

Thanks for joining the conversation, roger_cavanagh!

So that the Community can help you better, we need to know exactly which Canon printer model you're using.  We've made two models whose names could possibly match the one you mentioned, namely the imagePROGRAF PRO-300 and the imagePROGRAF GP-300.  Is it one of those or something else?

It would also help us to know which version of macOS you're using. That, and any other details you'd like to give will help the Community better understand your issue!

Thanks and have a great day!

Danny,

Thanks for the reply.

Apologies I’m a newbie here and to my imagePROGRAF PRO-300. I’m running macOS 14.5 Sonoma. I have a mesh network with Deco P7/M9 devices.

I have made some progress on my problem. I tried reinstalling PLPM, but that made no difference. With some trepidation I manually changed the IP address of the printer to …138 that Job Manager was reporting. This allowed me to successfully produce a print from PPLM. However, it does seem a potential issue to leave the printer as the only device on my wifi network not using auto-setup for TCP/IP. However, so far the only problem I have noticed is that the printer does not show as a connected device in the Deco app.

Colour me puzzled.

PPLM may be caching the old IP address. Try removing and re-adding the printer in PPLM, or set a static IP for the printer in your router to prevent future changes. This should ensure PPLM always connects to the correct address.

The posts above from @JeemVL and @breetmoon are correct.  🤣 However,  I just realized you both resurrected a one year old topic.  

You can easily assign the printer a static IP address on all routers (except starlink).   I'd go a step further and remove it from printers and scanners applet in Mac OS.  Use the minus key (-).  Restart your system and then install it as an IP printer using the address you assigned in your router.

In the add printer dialogue use the globe icon which is just to the right of the printer icon.  Specify the IP address as the destination.  You will note that the printer name dialog (below) will populate with the same IP address.  This field is editable, give your printer a friendly name something meaningful to you.  Select the printer driver in the drop-down below that you already have installed.

This will accomplish several things.  First, it will ensure that the printer always gets the same IP address on your network regardless of how often it's used, whether it goes to sleep or is turned off for an extended period of time.  Print jobs sent from the computer where it is installed will always use this IP address as the destination.  Further, any device that connects to the same network will always be able to find the printer at its statically assigned "destination IP".  This ensures a persistent and reliable connection.  Best of all this only has to be done once, set and forget.  😃

PPLM may be caching the old IP. Try removing and re‑adding the printer, or assign it a static IP via your router to keep it consistent. If you need reliable and flexible external access for remote management, whitelisting, or masking your network consider using a rotating residential proxy. LightningProxies offers over 10 million rotating IPs across 195 countries, with geo-targeting by country, state, city, or ISP, sticky or rotating session control, user‑pass or IP‑whitelist authentication, and unlimited bandwidth.
