Hi Tim,

thank you for reporting the issue!

Would you mind trying to reproduce the issue without kde-print-manager? Most of error messages comes from its library and the important message:

Mar 27 17:47:21 tigger2 cupsd[1069]: [CGI] Unable to create PPD file: Could not poll sufficient capability info from the printer (ipp://Canon%20TR8500%20series._ipp._tcp.local/, ipp://000000668D30.local:631/ipp/print) via IPP!

has the error reason which is not defined in CUPS...

But it seems your printer supports IPP everywhere (driverless standard) and the error happens during creating PPD from printer's IPP response.

How to reproduce without kde-print-mananger:

1) List the available devices:
$ sudo lpinfo -l -v

2) Find the device uri of your Canon printer (it looks it is ipp://Canon%20TR8500%20series._ipp._tcp.local/) in the list and try to add it as IPP everywhere model:
$ sudo lpadmin -p <name_of_your_choice> -v ipp://Canon%20TR8500%20series._ipp._tcp.local/ -m everywhere -E

If the queue is created correctly this way and you are able to print, I would say the error is on kde-print-manager's side.

If the error is reproducible even by those commands, please follow the steps https://fedoraproject.org/wiki/How_to_debug_printing_problems#B._Capture_whole_CUPSD_log , capture logs during the step 2) and attach the file as an attachment.

Ok looks like a KDE problem.

It happened after an update from f31 to f32 beta (not before).

Ran you commands 

Device: uri = ipp://Canon%20TR8500%20series._ipp._tcp.local/
        class = network
        info = Canon TR8500 series (driverless)
        make-and-model = Canon TR8500 series
        device-id = MFG:Canon;MDL:TR8500 series;CMD:PWGRaster,AppleRaster,JPEG,URF,PWG;
        location = 
➜  ~ ipp://Canon%20TR8500%20series._ipp._tcp.local/

zsh: no such file or directory: ipp://Canon%20TR8500%20series._ipp._tcp.local/
➜  ~ sudo lpadmin -p study -v ipp://Canon%20TR8500%20series._ipp._tcp.local/ -m everywhere -E

Added printer fine.

Just printed from libreoffice writer works fine.
Printing from chrome does not at present.

Not seeing anything on the KDE print queue.

It looks like you printed to temporary queue (which is used properly in libreoffice), not to permanent one which you created. And Chrome seems to try to print to temporary queue, but it is not able to work with it properly (Chrome issue).

This message is a reminder that Fedora 32 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '32'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 32 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 32 changed to end-of-life (EOL) status on 2021-05-25. Fedora 32 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
