CUPS -arm -airprint

Short: cups ver 2.2 vrs 2.3 , airprint works with latter, Brother mfc-J825 (on PBP)
Maybe I am doing something wrong (browsed is installed)

Long:  If you trace out the flow, after a few scripts you get to the filter driver, x86
I have never seen an armhf filter driver, except for reverse engineered efforts
Usually (99%?) airprint/bonjour/avahi is used (iphone, ipad, android)
There are 2 aspects, there has to communication to printer and generic ppd must be right
If communication is right, printer wakes up, no problem there, but no page emerges
If there  is no communication, cups complains, hard to ignore that
OR could it be a lack of "cups-filter-core-driverless" which doesn't seem to be in repo?

Re: CUPS -arm -airprint

OK, some more
If you are going to print with an arm device, you are almost certain to be using
airprint/avahi and the other tools
ippfind and ipptool are here, but driverless Command not found
driverless has a switch to make a ppd, I'm guessing this is the problem
Manjaro  has cups2.3, there is also a driverless command, airprint works

Re: CUPS -arm -airprint

More research
There are 2 ways to get a ppd, internally from cups, or with driverless
Cups, ver 2.2.4 and> can do it internally, I'm not sure when driverless appeared
Internally makes ippeve.ppd, driverless makes drvless.ppd, they are slightly different
Manjaro uses ippeve, debian10 uses drvless (without intervention)
Both work

Re: CUPS -arm -airprint

So I did "How to: Add/use Debian's....."  modified since 8-9 months have passed
And thought "better not"  ,, don't like the (3) changes  to libc
probably lead to much breakage, guess I have to wait for buster
Too bad, definately the quickest distro and despite the "retro" appearance
quite attractive (this on pbp, pinebook pro)
