I have an HP OfficeJet which only communicates with my phone after i turned the wifi on my phone off and the reconnect. This works 75% of the time. 24% of the time i have to reboot my phone, the printer or both. 1% of the time i am able to connect to the printer the first time the plugin starts. Several different phones, printing is oftrn more hadtle than not. Realky miss the old days when printers werent "smart" but instead reliable.
