[Comment 1 Daniel Pielmeier 2018-04-07 14:10:13 UTC]

I can not reproduce. Probably there are some unicode characters slipping in which can't be processed. Can you please try if the patch attached to this bug [1] fixes the issue.

[Comment 2 Nick Wiltshire 2018-04-07 17:11:42 UTC]

I can still produce the bug by removing the workaround.

Forgive me if I did this wrong:
mkdir -p /etc/portage/patches/net-print/hplip-3.17.10
cd /etc/portage/patches/net-print/hplip-3.17.10/
wget https://launchpadlibrarian.net/213208457/sixext.patch
emerge -va hplip

...

Created attachment 526812 [details, diff]
sixext.patch

Well the patch failed to apply, so the bug should be still there. I just applied it manually to test.

Use this one here. It should work as user patch.

[Comment 4 Nick Wiltshire 2018-04-07 17:56:52 UTC]

The attached patch fixed it.

[Comment 5 Daniel Pielmeier 2018-04-07 18:03:21 UTC]

Strange according to upstream this bug should be fixed.

[Comment 6 Daniel Pielmeier 2018-04-21 10:20:01 UTC]

This is fixed in Git with hplip-3.18.3-r1.

Thanks for the report.
