nl is the charactercodeof the first characterdefinedand n2 is the charactercodeof thelast characterdefined.nl and n2 mustbothbe between32 and 127or both be between 160and 255. n] must be equalto or less than n2. Use of charactercodes32 (space)and 127 (deletecode)shouldbe avoidedif possible.

Eachcharacters definedby anattributebyte(mO)and 11databytes

(ml, m2, ..... roll).

Themost significantbit of the attributebyte is 1 if the characteris an ascender(positionedentirelyabovethe baseline)or Oif it is a descender(descendingbelowthe baseline).The attributebyte also indicatesthe amountof whitespaceto theleft of the character(Oto 7 dots, specifiedby bits 4 to 6), andthe widthof the charactercell, includingthis space(4 to 15dots,specifiedby bitsOto 3). The left spaceandcellwidthattributesareusedonlyinproportionalspacing. Eachdatabyteindicateseightverticaldots,withtheMSBbeingthe top dot and the LSB the bottomdot.These correspondto pins 1 to 8 or 2 to 9 of theprint head,dependingon whetherthe characteris an ascenderor descender.
