Unable to create PPD file: Could not poll sufficient capability info from the printer
I am getting this error today, reported in 2020 #308.
Probably since one of last updates of packages.
I use Arch. The printer worked until recently, no issues. Even tested occasionally by removing it and adding it back.
I think it happened since the update with the recent CUPS security issue.

The error comes when I select from the list of drivers the one with XP 8700 driverless.
I selected IPP Everywhere, and I managed to add the printer, and seems to work fine.
Hi @madalinignisca ,
what's your cups-filters version?
What gives you when you do driverless cat driverless:ipps://EPSON%20XP-8700%20Series-D39FA4._ipps._tcp.local/? Please put the complete output into file and attach file here - in general follow this point and attach the files which got created.
The driverless command runs both libcupsfilters and libppd changes, so the output should have the same result as your error.
I briefly checked what is present on Arch Linux, and I saw there is not the latest CUPS release, which contains mirrored changes from libppd/libcupsfilters, so there is a chance IPP Everywhere won't work for you either. Hopefully with ipptool.attr file you'll provide we can be able to mimic your printer and figure out which attribute causes this - so either your device really contains invalid values and we have not caught this till this day (which will require you reporting to manufacturer and ask for firmware update), or there is an issue within our validation logic.
Hello, I got similar issue after updating to the latest CUPS drive on Fedora 41 with a HP OfficeJet Pro printer.
The solution is to update 'authselect' profile with the following command:
sudo authselect select local with-silent-lastlog with-mdns4
That will update /etc/nsswitch.conf with the following profile
# Generated by authselect
# Do not modify this file manually, use authselect instead. Any user changes will be overwritten.
# You can stop authselect from managing your configuration by calling 'authselect opt-out'.
# See authselect(8) for more details.
# In order of likelihood of use to accelerate lookup.

Then install the printer as usual. Full details from Fedora Magazine.
Hello, I have installed XUbuntu 24.04 and I am experiencing exactly this bug, unable to add my HP 9022 network printer which worked flawlessly with previous XUbuntu versions (and still works from other PCs in my household).
Unfortunately, I am unable to apply the authselect solution listed here:
$ lpadmin -p hp9020 -E -v dnssd://BonjourHPOfficeJetPro9022e._ipp._tcp.local/?uuid=72692038-5a09-4086-9ab9-369ab05254f8 -m everywhere

$ sudo authselect select local with-silent-lastlog with-mdns4
[error] /etc/authselect/authselect.conf is missing or unreadable, system was not properly configured by authselect.
[error] Refusing to activate profile unless overwrite is requested.
My /etc/nsswitch.conf looks like this:
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

Unfortunately I have no idea what "authselect" or "avahi" is. :(
