Several options for EPSON Ecotank ET-8500 do not appear when using ipp driverless. (Despite appearing in airprint) #915

Closed Bitwolfies closed 2 months ago

Describe the bug Certain options, such as the "best" quality option, or CD page size simply do not appear when using ipp and the aforementioned printer, despite them showing up fine when using airprint, which is just ipp again. To Reproduce Steps to reproduce the behavior:

Connect an ecotank et-8500
Try to switch quality to best
There is no best

Expected behavior Options like best quality to appear

System Information:

OS and its version: Arch, latest stable repos as of March 28th.
Application: KDEs print settings, cups web interface
CUPS version 1:2.4.7-2

Additional context It's interestingly able to generate the borderless page setups, which airprint does not.

Try the current git master, there were multiple changes for DPI detection and quality.

No effect, sadly.

Try cups-browsed then. It would add the printer by using cups-filters, not cups.

Been using browsed the whole time.

Can you attach the PPD file from /etc/cups/ppd and the output from the following command so we can duplicate your setup?

ipptool --ippserver epson.conf ipp://HOSTNAME/ipp/print get-printer-attributes.test

"HOSTNAME" is the hostname or IP address of your EPSON printer.

PPD: https://drive.google.com/file/d/1iMJ2UY9nnPCzc4IVty-AoDVNOY_8ki-D/view?usp=sharing

Unfortunately the output doesn't well, output. Screenshot_20240416_150159

The output from the ipptool command should end up in a file named "epson.conf".

So the PPD is actually generated by the "driverless" backend (as opposed to the built-in IPP Everywhere PPD generator) which could be an issue. It has cupsPrintQuality options for normal and high (best) quality, but I'm not sure how well this is plumbed up in the standard Linux print dialogs...

Using the following command to setup a print queue should yield the most predictable (and for our purposes in the CUPS project, the most supportable/testable) results:

lpadmin -p PRINTERNAME -E -v ipps://HOSTNAME/ipp/print -m everywhere

epson.conf.zip Heres the conf file, didn't know it just saved to home, ill try the new command and to force the ipp everywhere driver.

Bitwolfies commented 2 months ago

Indeed, the printer now has its full settings, I guess KDE just refuses to offer the ipp everywhere driver as an option in it's gui.

Bitwolfies commented 2 months ago

Names have a few parsing issues, but one thing at a time I suppose.

Bitwolfies commented 2 months ago

For now, Ill consider this closed, chalk it up to user error, thanks for the help! This was due to KDE not offering IPP everywhere as a section of your printer driver when onboarding.
