According to techniques described herein, print job attributes are checked to identify potential conflicts and potential invalid settings. According to one embodiment of the invention, a job setting manager process executing on a printing device is configured to examine and store print job attributes as detected by print interpreter modules. According to an embodiment of the invention, the job setting manager maintains a data structure comprising print job attributes, their values, and other information. As each interpreter module detects a job setting in the print data, the job setting manager receives this setting and its value and checks the data structure to identify conflicts between previously-set job attributes and whether the requested job attribute is supported by the destination printing device. According to an embodiment of the invention, if a conflict is identified, a notification is produced.
