Our company uses GutenPrint drivers in PrinterShare app for Android available through Google Play. After 5.2.8 GutenPrint driver update, we have received numerous reports from Canon printer users, who claim that communication between the app and the printers has ceased -- simply put, printers do not print at all.
The following drivers have been reporting as non-operational when used with our app: Canon PIXMA MX860, Canon PIXMA iP3100, Canon PIXMA MG4100, Canon PIXMA MG5300, Canon Pixma MG6200
The previous version Gutenprint 5.2.8-pre1 works wonderfully with the aforementioned printers.
We’re printing through Gutenprint system using IJS protocol (your IJS sever module) and PPD pritner description (obtained by using foomatic).
