Abstract
In a printer apparatus wherein information relating to character patterns to be printed is received from an external source and is analyzed and converted into intermediate coded data, which are stored into a temporary memory and are thereafter successively read from the temporary memory to produce bit-map image data representative of the character patterns to be printed for each page of printed output, whereupon the bit-map image data is stored into a bit-map memory by referring to a font memory and the character patterns are printed on the basis of the bit-map image data read from the bit-map memory for each page of printed output, a method of conveniently converting the information received from the external source into the intermediate coded data, storing the intermediate coded data into the temporary memory and thereafter storing bit-map image data into the bit-map memory in accordance with the intermediate coded data read from the temporary memory. The information received from the external source is converted into the intermediate coded data preferably such that the intermediate coded data is particularly useful for having the character patterns printed in any desired orienta…
