Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for enveloping a thread of execution within an IDT-based secure sandbox. In one aspect, embodiments of the invention provide a method performed in a computer system, the method receiving an instruction from an execution thread where the computer system can be configured for redirection of instructions from the execution thread. The method can determine whether the instruction includes at least one of an interrupt instruction, a system call instruction and a system enter instruction. In response to determining that the instruction includes at least one of the interrupt instruction, the system call instruction and the system enter instruction, the method can further: (i) eliminate the redirection, (ii) modify a stack to specify return of control, and (iii) thereafter, pass the control to an operating system kernel.

Handling instruction received from a sandboxed thread of execution

Methods and apparatus implementing a technique for printing to a selected destination in a computer system. A centralized print manager provides the implementation and control of operation for print services, such as tile printing or color separations. In general, in one aspect, the technique includes: generating print events to provide a specific print service to a client application, where the print events request information from the client application according to the specific print service; and receiving responses to the print events from the client application, where at least one response includes print data to be printed to a destination.
