Also ‘foomatic-filters’.

I can definitely understand the usability argument.  The counter
argument would be this:

--8<---------------cut here---------------start------------->8---
$ guix size cups-filters | tail -1
total: 270.4 MiB
$ guix size cups-filters escpr hplip foomatic-filters | tail -1
total: 569.5 MiB
--8<---------------cut here---------------end--------------->8---

I think carrying all this could make ‘guix system reconfigure’
heavyweight for many—lots of unnecessary downloads/rebuilds, etc.

What do people think?

I suppose on Debian etc., one has to explicitly install the right
packages, no?

Dear,

What is the status of the bug #30500 [1]?  It is tagged 'moreinfo' and
now a bit old.  It is about the addition of the two packages 'escpr' and
'hplip' to the service 'cups'.

It's since improved.  Probably thanks to hplip-minimal, whilst the 
newer Samsung SpliX package adds a mere 0.2 MiB:

  λ guix size cups | tail -n 1
  total: 279.5 MiB
  λ guix size cups-filters escpr hplip-minimal foomatic-filters 
  splix | tail -n 1
  total: 405.4 MiB (+45%)

‘Lots’ is way overblown.  This is it:

+/gnu/store/44xzcm69lmy71ydrnmv4plzxc26rk0dc-splix-2.0.0-315
+/gnu/store/amahw2r0b7fjqphisv8c0f6w77qac3c0-hplip-minimal-3.20.9
+/gnu/store/jqqf3xzs4sjdvnvddpk3pgx8g2rn9db3-foomatic-filters-4.0.17
+/gnu/store/w3rqls7rxri89xmi02yw8irycnf5zia1-escpr-1.7.7
+/gnu/store/9bfxyfqx12mnxwh715y23djnp239qh1b-libusb-1.0.23

+/gnu/store/8zvc5mvk0xm3ygrxsgpyy5ilxb5rzjry-perl-5.30.2

With the last 2 (3?) almost certainly already installed, this is 
not unreasonable for ‘cups-service-type actually prints, even if 
you visit grandma’.

Visit grandma,

Grandma’ is lost, on one hand +45% and on the other hand not
unreasonable. :-)

Does it make sense to apply the patch?  From my point of view, yes.

Hi,

Does it make sense to apply the patch and close this old bug?

From my point of view, yes for the two. ;-)


All the best,

I no longer have the original bug report in my main mail folder, that's
how old it is :). Lets add a couple more, printing sucks a lot as it
already is. I don't think it's any worse than, say, adding
glibc-locales@2.29 by default. Just make sure the documentation is
updated accordingly.

I vote yes

I could rebase the patch and add documentation.  But I am not using
printing or services (foreign distro) so I would be able to test it.

Please beat me at this. :-)
