HP Photosmart b109a-m: Scanner not recognised in HPLIP 3.19.

A patch is attached which re-adds the Photosmart b109a-m to models.dat.

Note, that in HPLIP 3.19 also other printers seem to have disappeared from models.dat, e.g. '[hp_colorpro_plotter]'.

A quick diff reveals that a subset of the following printers has disappeared:

(I wrote subset, because a few of them have not disappeared but just have changed position in the file such that diff did output them. I did not take the work to remove them from the list -- I do not consider this my duty.)

As anticipated by Vier Eck, I can confirm that the above affects the [hp_laserjet_100_colormfp_m175nw] device, which is no more recognised after the stratification of models.dat

Can you please revert the stratification of `models.dat` from version 3.18 to version 3.19? It is very annoying that every update of HPLIP needs manual change of `models.dat` to make some printers working again, or the force to the older version 3.18 of HPLIP.

So, I manually re-added all the printer definitions removed from the `models.dat`. I also re-added `modelN=<string>` here and there, not really knowing what they mean exactly.

Here is my patch for `hplip 3.19.3`'s `models.dat` which re-adds the printers which were present in `hplip 3.18.12` but not anymore in `hplip 3.19.3` (attached and at http://ix.io/1HEt).

Yes this bug affects me too, i just found by myself the solution but spent hours..
Now everything is back to normal when manually editing the .dat file section which is missing.
This happened when upgrading Fefora 29 to Fefora 31 which installs hplip 3.20 and caused the issue in my linux box.

error: Unsupported model: Photosmart_B109a-m

Still works fine in Ubuntu 16.04 and 18.04 but is no longer recognized in 20.04

Problem still present with hplip 3.20.9.

Please fix, since it renders my scanner useless unless I do manual editing '/usr/share/hplip/data/models/models.dat' of as root _after upgrade of hplip_.

The fix is simple and was already posted here: https://bugs.launchpad.net/hplip/+bug/1821079/comments/1

I encountered this today on Ubuntu 20.04.3 LTS with hplib 3.20.3+dfsg0-2.

Printing more than one page always resets the printer and scanning is not possible. The patch fixes both issues for me.

Still present in hplip 3.21.

Please do fix this issues; who should be poked directly to get someone paying attention to this issue???
