Apple modifies some things in CUPS that affect GNU / Linux

Interesting news that I have read in slash, which I don't know if it's another dirty strategy on the part of Apple (as they do with their patents to prevent companies like Samsung from beating them in the market) and to what extent we will really be affected.

Apple bought the source code of CUPS and hired its creator in February 2007 Michael R Sweet, something I was totally unaware of. What they did now was remove the ability to communicate CUPS-to-CUPS to discover active printers available on the network, and manage this feature with DNS-SD, what do you use CUPS en Mac OS X. What happens then? Well in slash They explain it in detail:

This means that once support for connected printer browsing and discovery is discontinued in CUPS, automating this process will "require Avahi" to be active on both the server (that is, on the system hosting the CUPS queue) as well as the clients (that is, the systems that intend to print through it).

The problem is that apparently with Avahi, this feature is not fully functional. The good news is that these features (CUPS-to-CUPS) will continue to be maintained for OpenPrinting as an independent project.

What do you think?

    I found out that it was owned by Apple through this cups configuration page (http://localhost:631/). Where it says:

    CUPS is the standards-based, open source printing system developed by Apple Inc. for Mac OS® X and other UNIX®-like operating systems.

    Until reading this news, I did not know about openprinting, is it a project to replace CUPS or something like that?

    I can't stand Apple's pranks, his conspiracies make me nauseous. Microsoft at least doesn't sneak up on you, they're more direct.

    *** CUPS password (printers) in browser with Live USB / CD ***

    In some minimalist distro, printers are managed graphically (only) from the web browser, from the address or URL http://localhost:631/

    This is also possible from other distros that also have the option of managing printers from the control center. But there are operations that require entering username and password (eg adding a printer). If we are running Linux from a live USB or live CD by default we do not have a live user password and putting its name and leaving the password box blank does not work.

    The solution is to create a user (with a password) and add it to the lpadmin group. This can be done from the control center graphically. Also from the terminal, with these commands (a distribution is assumed that requires sudo to be prepended so that the default live user can execute commands that require root or superuser permissions):
    sudo adduser tester
    (instead of tester you can put the desired name)
    (you will have to put a password and repeat your introduction)
    sudo adduser lpadmin tester
    (instead of tester you have to put the same name as in the previous command)

    Now it is enough to put the chosen username and password when CUPS requests them from the web browser.
