Comment 23 for bug 1883898

One concrete example: `drv:///hpcups.drv/hp-laserjet_professional_p1107.ppd`

In 3.20.5, in hpcups.drv, it had as NickName:

  "HP LaserJet Professional p1107, hpcups $Version, requires proprietary plugin"

… this was changed in 3.20.6 to:

  "HP LaserJet Professional p1107, hpcups $Version"

… and unchanged in 3.20.9.

In models.dat, for that model, 3.20.5 had

  plugin=1
  plugin-reason=1

… this was changed in 3.20.6 to

  plugin=0
  plugin-reason=1

… and unchanged in 3.20.9.

But printing to this driver/printer gives a filter error:

  STATE: +hplip.plugin-error
  prnt/hpcups/HPCupsFilter.cpp 490: m_Job initialization failed with error = 48

(see https://salsa.debian.org/printing-team/hplip/-/jobs/937420 )

So although this was fixed for several printers, it certainly wasn't for all printers.
