Abstract

Much research and development has been devoted to making computer printers quiet. Even with the advances in noise control for printer devices, many printers still generated sufficient noise to be distracting to an office user during a telephone conversation. Some users may be using older model printers which are not affixed with noise reduction enhancements. Often telephone calls are received at inopportune moments, i.e., documents printing. Current art requires the user to physically interact with the computer or application, e.g., take the computer off-line. In addition, users must manually reactivate to the printer after hanging up the telephone. A mechanism is desired that automatically suspends a printer upon a user activating a telephone line.

Printer Disengagement via Telephone Activity Detection

      Much research and development has been devoted to making
computer printers quiet.  Even with the advances in noise control for
printer devices, many printers still generated sufficient noise to be
distracting to an office user during a telephone conversation.  Some
users may be using older model printers which are not affixed with
noise reduction enhancements.  Often telephone calls are received at
inopportune moments, i.e., documents printing.  Current art requires
the user to physically interact with the computer or application,
e.g., take the computer off-line.  In addition, users must manually
reactivate to the printer after hanging up the telephone.  A
mechanism is desired that automatically suspends a printer upon a
user activating a telephone line.

      This article describes a mechanism which detects the activation
of the telephone answer mode, e.g., detection of the S2 modem
register being TRUE.  Upon detection of telephone activity a print
spooling service is disabled until the telephone is disengaged, i.e.,
hang-up detected.  A registration service permits users to registered
printing devices according to their applicability to interfere with
telephone conversions.

      Print requests are routed to the invention's print spooler.
Upon the user answering the telephone, an activation table is
searched for currently executing printer jobs, i.e., detection of a
registered print device...
