摘要 <p>A printer with media supply spool adapted to sense type of media, and method of assembling same. A supply spool (120) to be loaded into the printer (10) is adapted to sense type of a media ribbon (125) thereon. The supply spool comprises a shaft (310) having a supply of media ribbon wound thereabout. A transceiver unit (330) is disposed proximate the shaft. The transceiver is capable of transmitting a first electromagnetic field (335) and sensing a second electromagnetic field (337). A transponder (340) including a semi-conductor chip is integrally connected to the shaft and has encoded data previously stored therein indicative of the type of media ribbon. The chip is capable of receiving the first electromagnetic field to power the chip and then generating the second electromagnetic field as the chip is powered. The second electromagnetic field is characteristic of the data previously stored in the chip. The transceiver unit senses the second electromagnetic field, which second electromagnetic field has the data provided in the chip. The printer then operates in accordance with the data sensed by the transceiver to produce quality prints consistent with the type of donor being used. &lt;IMAGE&gt;</p>
