I have iPhone 15 pro running iOS 17.6 and a Canon imageClass LBP632Cdw laser printer. I was able to AirPrint for the first 10-15 minutes of setting up the printer. Once the printer enters sleep mode, my iPhone can no longer detect any AirPrint Printers. However, all my pcs, laptops, and macbooks can print without issue. The only way to get it to work is by logging into the printer on a pc and restarting the device or unplugging and plugging it back in. This will only temporary fix the problem, because after the printer enters sleep mode you can no longer use AirPrint. The problem seems that ios and mobile devices cannot wake the printer.
There seems to be a lot of others having this issue and Canon still has not resolved it...if you advertise this on your box then it should work!
What I have already done for troubleshooting:
On my iPhone / iPad
- Did all software updates (UNSUCCESSFUL)
- Disconnect and reconnect to WiFi via Airplane Mode (UNSUCCESSFUL)
- Forget Network and reconnected to it (UNSUCCESSFUL)
- Reset all Network settings (UNSUCCESSFUL)
On my Canon / Brother Printer
- Restarted the device (UNSUCCESSFUL)
- Unplugged and plugged back in (TEMPORARY FIX, until printer entered sleep mode)
- Removed from network and reconnected (UNSUCCESSFUL)
- Verified AirPrint is turned On (UNSUCCESSFUL)
On my Router (google nest pro)
- Restarted Entire Network (UNSUCCESSFUL)
- Unplugged bother Router / Modem (UNSUCCESSFUL)
NOTE: This same thing occurs with my old Brother printer.
