Vnitrni zapis
Escape sekvence
ESC s <vynechat> - mezera n bodu
ESC p <filename> <x> <y> obrazek na souradnicich x a y
ESC e - konec stranky (jako prvni v textu)
ESC h - horizontalni rule (jako prvni v textu)
ESC l <skip> - konec radky (skip je pocet vynechanych bodu)
Zapis cisla - to je hexa cislo od 1-255 pokud se nevejde do rozsahu je po 256
pridana dalsi hodnota, tj 255 se zapise jako 255,1,
350 se zapise jako 255,96,
