Select font parameter handler. Called on the byte immediately following a 26 control code. Copies the six-byte font configuration for the selected font index (0–3) from the table at FontConfig_Table into the font state at 32780 and loads the font bitmap pointer into 32776.

| PrintHandler_SelectFont | 36551 | LD B,4 | B=4 (mask limit: font indices 0–3). | |
| 36553 | CALL PrintHandler_MaskParam | Call PrintHandler_MaskParam to reset PrintState_Handler and mask B to the font index. | ||
| 36556 | LD H,0 | H=0. | ||
| 36558 | LD L,B | L=B (font index as a 16-bit value in HL). | ||
| 36559 | LD DE,36838 | DE=FontConfig_Table (font configuration table base). | ||
|
Multiply the font index by 8 (the size of each font table entry) to compute the byte offset into the font table.
|
||||
| 36562 | ADD HL,HL | Multiply HL by 8 (three left shifts). | ||
| 36563 | ADD HL,HL | |||
| 36564 | ADD HL,HL | |||
| 36565 | ADD HL,DE | HL=FontConfig_Table + (font index × 8) — pointer to the selected font entry. | ||
| 36566 | LD DE,32780 | DE=32780 (font state destination). | ||
| 36569 | LD BC,6 | BC=6 (six bytes of font configuration to copy). | ||
| 36572 | LDIR | Copy six bytes of font configuration to 32780–32785. | ||
| 36574 | LD E,(HL) | Read the two-byte font bitmap pointer from bytes 7–8 of the entry. | ||
| 36575 | INC HL | |||
| 36576 | LD D,(HL) | |||
| 36577 | LD (32776),DE | Write the font bitmap pointer to *PrintState_FontPtr. | ||
| 36581 | RET | Return. | ||
