I am currently trying to configure my Epson printer on Guix system usingsystem-config-printer. The printer is connected via USB and isautomatically detected in the dialog window that opens if I click on "Add". I select the printer from the list and click on "Forward", then I enter the printer name, a description and a location in the section "Describe Printer". However, if I click on "Apply", the following errormessage is printed:
I was unable to reproduce this at all, albeit without an Epson USB printer connected, of course.
My steps through the CUPS Web interface:
- Administration
- Add Printer
- Internet Printing Protocol (ipp)
Continue
- Connection: "ipp://fake.printer/print/Print"
Continue
- Description, Location: "test"
Share This Printer unticked
Continue
- Make: Epson
Continue
- Model: EPSON ET-2600 Series , Epson Inkjet Printer Driver
(ESC/P-R) for Linux (…)
- Then accept all default options.
Result attached. At no point do I get an error.
Interestingly, my CUPS only ever looks in the right location for
epson-escpr-wrapper:

--8<---------------cut here---------------end--------------->8---I can even print a test page (from the Maintenance drop-down). Of course it fails to connect to the printer, but still the filter seems to run perfectly:
