Abstract
An embodiment of the present invention comprises a system that causes a printer carriage to scan from a reference position to a second position. The status of the peripheral is monitored by the host computer with detectors that can sense the position of the carriage when at the reference position and the second position. A count is made of the number of clock pulses that occur during a time the carriage scans from scans reference position to the second position. A lookup table is then used that is indexed by the number of clock pulses. This provides a set of parameters the host computer will need to have available to use the peripheral right.
