ABSTRACT:
Thermal recording comprising the steps of supplying input data I.sub.u to a processing unit (23) of a printer having a thermal head with a plurality of heating elements; storing input data of a line into a buffer memory (24), further called input line data I.sub.l ; converting (25) the data I.sub.l into serial configurated data I.sub.s ; mapping (32) the data I.sub.s with resistance compensation data into power mapped data I.sub.m ; shifting the data I.sub.m into a shift buffer memory (26), further called shifted power mapped data I.sub.m' ; counting (33) a number N.sub.s,on of simultaneously activated heating elements; adapting (34) a strobe duty cycle .delta. (35) in accordance with N.sub.s,on, further called voltage corrected strobe duty cycle .delta..sub.v ; providing (36) the .delta..sub.v and the data I.sub.m' to the heating elements for reproducing the line of an image.
