Description:

In HPLIP 3.19, the section '[photosmart_b109a-m]' was removed from '/usr/share/hplip/data/models/models.dat' (only section '[photosmart_b109a_series]' is there, but that is not sufficient to match the device for scanning).

In HPLIP 3.18, both sections were present.

This makes the device not recognised by HPLIP tools:

`hp-check -t` prints out

error: Unsupported model: Photosmart_B109a-m

and the device is also not recognised for scanning (scanimage -L does not find it).

If I manually re-add the section '[photosmart_b109a-m]' to '/usr/share/hplip/data/models/models.dat' everything works again.

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.)

Steps to reproduce:
Have a printer/scanner that identifies itself as 'Photosmart B109a-m' connected via USB. Have HPLIP 3.18.x installed. Run `scanimage -L` or `hp-check -t` and note that the device is recognised and SANE could scan from it. Upgrade to HPLIP 3.19.1. Run `scanimage -L` or `hp-check -t` and note that the device is not recognised and SANE could not scan from it.
