ESC ! P1 Select Multiple Print Mode Notes: - This Command defines one or more characters in a RAM character
P1 selects: table.
Bit0 = 0 : 10 cpi (Pica) - All User Defined Characters are erased when the printer is switched
Bit0 = 1 : 12 cpi (Elite) off.
Bit1 = 1 : proportional - Set the Interface Buffer to 1k or 8K (max 50 defined char in LQ, 128 in
Bit2 = 1 : Condensed draft), or use a RAM card for up to 128 User Defined Characters in LQ.
Bit3 = 1 : Emphasized - Set maximum every second dot to "1" in a horizontal line !
Bit4 = 1 : Double Strike - User Defined Characters can be defined in four different print modes:
Bit5 = 1 : Double Width resolution (vertical x horizontal)
Bit6 = 1 : Italics Normal Size with Draft: 24 x 15
Bit7 = 1 : Underline Normal Size with LQ / proport.: 24 x 37
ESC $ P1 P2 Set Absolute Horizontal Position Sub-/ Superscript with LQ / proport.: 16 x 37
