Abstract: A method of converting data for printing using a computer is disclosed herein. The computer comprises a first processor having first memory associated therewith and second processor having second memory associated therewith. The method includes converting at least a portion of a page in a printer defined language to a display list using the first processor; transferring the display list to the second memory; converting the display list to at least one bit map using the second processor; and transferring the bit map to the first memory.

Abstract: A blocking system intercepts communications between a software program and an operating system in order to handle blocking and unblocking of event signals. The blocking system intercepts system calls to the operating system requesting the blocking and unblocking of event signals and keeps track of which event signals are blocked and unblocked without delivering the system calls to the operating system. The blocking system also intercepts event signals from the operating system and only allows unblocked event signals to pass to the software program. Blocked event signals received by the blocking system are discarded until the program unblocks the blocked event signals. After unblocking an event signal, the blocking system determines whether a corresponding event signal was previously received and blocked. If so, the blocking system transmits a signal indicating that the event corresponding to the event signal occurred.
