Linux distribution: Arch Linux

Symptoms:

1. hp-setup can not detect the p1102w printer when using USB connection.
2. hp-setup can not find the p1102w printer through manual WiFi IP connection.
3. hplip is at version 3.19.x

Solution: Open the file /usr/share/hplip/data/models/models.dat, and search for the entry with keyword p_1102w. There should be an entry with the name hp_laserjet_professional_p_1102w. See the problem here? It should be hp_laserjet_professional_p1102w. No underscore should be present between p and 1102w. So the solution is simple: just remove the underscore. Also, inside the entry, there’s a property: model1=HP LaserJet Professional P 1102w Printer. There’s an extra space between P and 1102w. I’m not sure if this property will affect the functioning of the printer, but I prefer to remove the space. So that property will be: model1=HP LaserJet Professional P1102w Printer.
