Hello,I've developed a print server for a photo booth application that:Configures connected USB printers to be shared via CUPSUses Avahi to publish those shared printers over BonjourIn the app I'm using, I can select the printers shared over Avahi in the Printer Picker Controller, but when I attempt to send a job directly to the printer, I get an error:ErrorNo printer found. Showingdefault printer selectionview.After I acknowledge the error, the Printer Picker Controller is displayed again, this time with the job loaded, and the previously selected printer is already selected. I can simply tap "Print" and the job completes.If I choose any other AirPrint printer that might be on my network, I do not receive an error. Instead, I get acknowledgement that the job has been added to the print queue.Something about my CUPS/Avahi setup is preventing jobs from being sent directly to the printer; has anyone ever experienced this and what was the workaround?
