Escape Sequence Mnemonic Function
ESC & NUL P1 P2 P3 P4 P5 v1 .. vn Define User Defined Characters
P1 = first code table position
P2 = last code table position (P1 = 0/0...P2) (P2 = P1...7/F)
P3 = front space (P3 = 0/0...5/0)
P4 = body length Draft: (P4 = 0/0...0/F) LQ: (P4 = 0/0...2/5)
P5 = rear space (P5 = 0/0...5/0)
v1 .. vn = binary data in hex (vn = 0/0...F/F)
Notes:
- This Command defines one or more characters in a RAM character table.

All User Defined Characters are erased when the printer is switched off.

Set the Interface Buffer to 1k or 8K (max 50 defined char in LQ, 128 in draft), or use a RAM card for up to 128
User Defined Characters in LQ.

Set maximum every second dot to "1" in a horizontal line!

User Defined Characters can be defined in four different print modes:

resolution (vertical x horizontal)
Resolution (vertical x horizontal)
Normal Size with Draft: 24 x 15
Normal Size with LQ / proportional: 24 x 37
Sub-/ Superscript with Draft: 16 x 15
Sub-/ Superscript with LQ / proportional: 16 x 37

The characters can only be activated in the same mode as defined.

The character layout is coded in three bytes (24 bit vertical) or two bytes (16 bit vertical) per column, top to
bottom.

To print the character change to the User Defined Character Set with ESC % .
Example:
vertical box, normal size with draft at code table position "41" (P3=8, P4=5, P5=8)
hex: 1B 26 00 41 41 08 05 08 FF FF FF 00 00 00 80 00 01 00 00 00 FF FF FF
