| PrintHandler_Paper | 36413 | LD B,8 | B=8 (mask limit for PAPER colour range 0–7). | |
| 36415 | CALL PrintHandler_MaskParam | Call PrintHandler_MaskParam to reset PrintState_Handler and mask B to the colour value. | ||
| 36418 | LD A,(32772) | A=*PrintState_Attr (current attribute byte). | ||
| 36421 | AND %11000111 | Clear the PAPER bits (199 = keep INK, BRIGHT, FLASH). | ||
| 36423 | SLA B | Shift B left three positions to move the colour into bits 3–5. | ||
| 36425 | SLA B | |||
| 36427 | SLA B | |||
| 36429 | OR B | Write the new PAPER colour into bits 3–5. | ||
| 36430 | LD (32772),A | Write the updated attribute byte back to *PrintState_Attr. | ||
