"apt upgrade" removes CUPS printers definitions

[andy55]

Hello,

I have defined printer in my debian buster. But whenever I run "apt update & apt upgrade" and there is some upgrade for cups package the printer definitions are deleted.
It happened twice or three times so far.
How can I "lock" printers definitions ?

Thanks

This may not be the answer you are looking for and maybe I don't understand your question but here goes.

Printers come able to use a range of dns and are assigned a fresh one each time you boot. Years ago I went into my printer and nailed the dns to just one. Since then we have gone through different machines and many upgrades without losing printer location.

Perhaps, you have made "printer definitions" by hands in the files, which are created automatically by cupsd.
Any tweaks must be executed in CUPS interface.

Peter.

Like Bulkley, I haven't any idea what you mean by "printer definitions". Perhaps you
could explain what happens? What do you see?

BTW, CUPS on stable is hardly ever upgraded.

I love it

Three answers and no one has a clue what the OP is asking.

Cups has updates quite often on my sid and I have never seen any "definitions" or anything else change.

Hey OP, definitely define "definitions".

How do you print to your printer using CUPS ? By adding a printer. I used "defined printer" intead of "added" - is it what confuses you ?

BTW todays upgrade:
