It is indeed the case, with the pointy haired boss being the missus and the 
box in question a production desktop. :-))

I have to admit that I can't recall messing up with the ppd files, or indeed 
ever using hpijs on this box.

A couple of months ago the akonadi DB went sideways and kmail played up as a 
result.  Again I was suspicious of btrfs, but neither the logs nor fsck showed 
up anything.

The OS is on a single SSD (no RAID), with some caches and busy fs mounted on a 
spinning disk.  I have some backups in case of DR, but after a while a 
corrupted fs will have migrated to the back ups.

I take it "btrfs scrub" didn't turn up anything, or is that what you meant by 
fsck?

With btrfs, if there really was silent corruption, you wouldn't be able to 
access the file in the single disk case, so no, I don't think it actually 
would propagate to the backup (although perhaps you don't use btrfs 
exclusively, in which case it of course could).  Though keep in mind that 
corruption can happen in a variety of ways, e.g., application-level or 
firmware bugs.

Thank you wabe.  This is just how I recalled this should be and confirms my 
suspicions that hpijs is not needed.  I am at a loss as to why 930c suddenly 
disappeared from the list of available drivers.  I am also at the latest 
stable hplip-3.14.10.

Could this be btrfs playing up and messing up cups?  O_o

I get the same option just trying to modify my current printer.  It
doesn't list anything, it just shows the printer I currently have set
up.  Even if I tell it I want to add another printer, it still shows my
current printer.  I can't find a way to get it to list them.  Maybe it
is a setting somewhere that I have that makes mine work different.

OK, I managed to get 10 minutes access to the offending box and I remerged 
hplip.  Guess what?  The 930c driver re-appeared on the list.  So I am now 
doubly paranoid that the btrfs is playing up ...

 I was going to try and test this.  I try to help when ever I can.  Thing
 is, the way CUPS works here, you have to have the printer connected to
 set it up.  I can't find a option to set up a printer that is not
 connected during the set up process.  Maybe I am missing something.  o_O

 Maybe someone else who has that printer can test it.  We hope.

When you said "I managed to get 10 minutes access to the offending box"
I figured it wasn't yours, that it had users, and you were the guy with
the problem of sorting it out, and you needed some pointy haired bosses'
permission to do it at all.

Seems that's not actually the case?

I don't have USE flag hpijs set for hplip (3.14.10) and when I modify 
my printer, there are two lines for HP DeskJet 930C shown up:

HP Deskjet 930C Foomatic/cdj550 (en)
HP Deskjet 930c, hpcups 3.14.10 (en)

My USE flags for hplip are:

X doc hpcups libnotify qt4 scanner snmp -fax -hpijs -kde -libusb0 -minimal

I was going to try and test this.  I try to help when ever I can.  Thing
is, the way CUPS works here, you have to have the printer connected to
set it up.  I can't find a option to set up a printer that is not

Thank you Dale,

You don't have to complete the setup of the printer.  Just select Modify 
printer and 'try' to change its driver from the dropdown selection.  You don't 
need to actually change it - just look in there if DeskJet 930c is listed.  
Assuming of course that your hplip was compiled with USE="-hpijs".

My 930C is a USB printer, but I have a little ethernet to USB printer server 
that I access it through.  This is a monodirectional lpd server, so all the 
hplip GUI to report printer status is not working.  It doesn't bother me as 
printing is a rare occasion and all users know what to do if it runs out of 
ink.

Printing was all working fine on this PC until a couple of days ago, so I 
wonder if I removed something in /etc/portage/* to cause this ...
