Hi,

I am trying to setup a HP Photosmart C3100 printer on Guix and when
trying to print the job fails with


       Processing - "Color Manager: no profiles specified in PPD


Also when I try to configure the printer from the web interface
( http://localhost:631/printers ), see the error in the log
E [19/Jan/2019:22:00:23 +0100] Unable to create "/gnu/store/qv49wv0b5s2jmn4ln3r14v4bks18wqp0-cupsd.conf.N": Read-only file system

Can you give me a pointer how I could fix that?


I tried adding the printer with hplip-minimal and now also with hplip
hp-setup, but the error exists in both setups.


Best wishes,
Arne
