Comment 31 for bug 59409

My HP LaserJet 3390 produces the following output:

till@till-laptop:~/ubuntu/hplip/svn/pkg-hpijs/hplip/build-area$ /usr/lib/cups/backend/hpfax
direct hpfax:/usb/HP_LaserJet_3390?serial=00CNMJP81545 "HP Fax" "HP LaserJet 3390 HP Fax HPLIP" "MFG:HP;MDL:Fax;DES:HP Fax;"
till@till-laptop:~/ubuntu/hplip/svn/pkg-hpijs/hplip/build-area$

This is how it should be. It makes CUPS assigning the old fax PPD to this device.

For the HP LaserJet M2727 (and any other model with the new color fax capability) I expect the following (I do not have this printer, I only show how it should look like):

till@till-laptop:~/ubuntu/hplip/svn/pkg-hpijs/hplip/build-area$ /usr/lib/cups/backend/hpfax
direct hpfax:/usb/HP_LaserJet_M2727?serial=XXXXXXXXXX "HP Fax 2" "HP LaserJet M2727 HP Fax 2 HPLIP" "MFG:HP;MDL:Fax 2;DES:HP Fax 2;"
till@till-laptop:~/ubuntu/hplip/svn/pkg-hpijs/hplip/build-area$

The PPD should have as model name, short nick name, and nick name "HP Fax 2" and as device ID "MFG:HP;MDL:Fax 2;DES:HP Fax 2;". Then CUPS would perfectly assign always the correct PPD file.
