Abstract

A mapping-type data signal optimizer performs a DEVICE-SPECIFIC ATTRIBUTE ELIMINATION routine. If field attributes in an outgoing signal do not affect the appearance of a data display on, or the operational characteristics of, a peripheral device receiving the outgoing signal (e.g., field attributes are essentially meaningless on printers), then the outgoing signal is reformed so as not to include those attributes.

Claims

1. A computer device comprising program instruction statements which, when executed by a programmable machine, result n the performance of the following steps:

intercepting an outgoing signal directed to a peripheral device, said outgoing signal including zero or more display attributes;

checking a table to determine whether said peripheral device supports said display attributes; and

if said peripheral device does not support display attributes, constructing a new outgoing signal with no said display attributes and directing said new outgoing signal to said peripherals device.

2. A program storage device readable by a programmable machine and tangibly embodying a program of instructions adaptable to cause the machine to perform the method steps of claim 1.
