Subject: [PATCH 0/4] hplip: Enable network support
Date: Wed, 26 Feb 2025 11:40:54 +0000

Hello Guix,

currently, our hplip package does not build the network support.  This causes
the following:

* the 'hp-setup' utility does not allow to configure network-connected HP
  printers or all-in-ones.

* printing on network-connected HP printers through hplip (i.e. using a url
  like 'hp:/net/...' for the connection in CUPS) does not work.

* scanning with sane on a network-connected HP all-in-one is not possible
  using a url of the form 'hpaio:/...'.  Such scanners are also not
  automatically found by sane.


The following patch-series fixes these issues by building the network support
in hplip. After reconfiguring my system with these changes I am able to print
and scan using an HP OfficeJet Pro 8020 series all-in-one connected to the
local network.

Thank you in advance for your feedback!

best,
Lukas

* gnu/packages/cups.scm (hplip-minimal): Disable networking.
[arguments] <#:configure-flags>: Add "--disable-network-build".  The "lite
build" of hplip is incompatible with the "network build", so disable
the latter explicitly.
[inputs]: Rephrase the inputs as a positive list and remove net-snmp, openssl,
and avahi (inherited from hplip).
