Appendix E EPSON LQ 2550 and ESC/P2 Quick Reference
E-8
Table B-5 (Cont.): Horizontal Form Handling and Printing Modes
Escape Sequence Function
ESC & NUL P1 P2 P3 P4 P5 v1 .. vn Define User Defined Characters
P1 = first code table position
(P1 = 0/0...P2)
P2 = last code table position
(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)
Normal Size with Draft: 24 x 15
Normal Size with LQ / proport.: 24 x 37
Sub-/ Superscript with Draft: 16 x 15
Sub-/ Superscript with LQ / proport.: 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 % .
Examlpe: vertical box, normal size with draft at code table position "41"
(P3=8, P4=5, P5=8)
