Abstract
A thermal line printer is provided in which required printing is carried out by developing a thermal recording paper under heat generated by heat generating elements or by melting a heat-meltable ink under such heat to deposit melted ink on a recording paper sheet. The thermal line printer includes external memory means having a function to store print data for two or more dot lines as corrective print data and capable of asynchronously performing its write and read functions. Furthermore, both print data processing and control of the external memory means are carried out mainly by a hardware arrangement, whereby the thermal line printer is inexpensive, provides high print quality, and has high-speed printing capability.
