HP OfficeJet Pro 8600 every now and then decides not to respond to Print Command (when there's a deadline!) Dialog box (print queue) shows document "Printing - Connected to printer" or "Ready to pring - 1 page" - but it isn't! Doesn't matter if it's WiFi or USB connected.
MacBook, 10.11.6.
Every time I buy a printer, it's from a different company, hoping to find one that's dependable. This has been better and lasted longer than others - 3 years, I suppose that's beyond expected life! Still, I'll try Epson next, not HP. If my car only worked most of the time, there would be lawsuits! I don't know why we allow less dependability for tech products - just as crucial, anymore, to daily business! I'll pay more, just give me something that I can trust to work!
