According to aspects of the embodiments, there is provided methods of controlling operation of a printer, apparatus and computer-readable medium. The embodiments control operation of a printer by receiving a print command for printing from a user, and displaying a print user interface including selectable document settings and context based restrictions. Context based restrictions allows a system administrator to flexibly manage users access to a device features and capabilities. A variety of restrictions can be specified including time-based, capacity-based, and application-based. This invention also prevents the user from submitting a job with a restricted feature. Advantages are a clear, understandable presentation of restrictions to the user so the user knows what features the user cannot access.

Printer driver with context based restrictions

An apparatus and method share and manage passcodes across multiple printing device drivers. The method can include providing, on the electronic device, a first printing device driver for a first printing device and a second printing device driver for a second printing device. The first printing device driver and the second printing device driver can access a common secure printing device passcode storage location for secure printing device passcodes. The method can include storing at least one secure printing device passcode in the common secure printing device passcode storage location. The method can include displaying secure print information to the user in response to receiving a secure print input. The method can include sending a secure printing device passcode over the network interface to a printing device to securely print the document.

What is disclosed is a novel system and method for ensuring that plug-in DLLs are not unloaded and reloaded repeatedly during the course of a single user-initiated operation. A base driver process loads a plug-in DLL. If a manager thread responsible for this plug-in does not exist then a reference count for the plug-in DLL is incremented. Incrementing the system reference count ensures that the plug-in DLL remains loaded between base driver calls for all of the user-initiated operation by preventing the operating system from unloading the plug-in DLL. A manager thread is then created. The manager thread monitors active COM objects and checks if the base driver is still in memory. If no COM objects are found to be in use after a predetermined amount of time or if the base driver is no longer loaded in memory, the system reference count is decremented. The manager thread then exits.
