These are the printer control codes for IBM/Epson - compatible printers.

Hex Dec  Description
                                                                         
07    7  (BEL) sounds a beep
09    9  (HT) move to next tab stop  (See ESC D)
0a   10  (LF) Linefeed: moves the paper up on line
0b   11  (VT) feed lines to next vertical tab stop (See ESC B)
0c   12  (FF) Formfeed: advance to top of page (See ESC C)
0d   13  (CR) Carriage Return: prints line (no linefeed)
0e   14  start DOUBLE-WIDTH printing (ends on CR or LF.  See ESC W)
0f   15  start COMPRESSED mode printing
11   17  select printer
12   18  end COMPRESSED mode printing
13   19  deselect printer
14   20  end DOUBLE WIDTH printing
18   24  (CAN) clears the printer buffer
1b   27  (ESC) lead-in code for multi-character sequences (See below)
7f  127  (DEL) clears the printer buffer

These ESC sequences are arranged by rough functional groups.  Values shown
in the form  n  indicate binary codes.

Line Spacing / Page Length
ESC 0      1b 30        8 LPI: start 1/8-inch line height
ESC 1      1b 31        start 7/72-inch line height

ESC 3  n   1b 33 xx     set variable line spacing to  n /216-inch
ESC J  n   1b 4a xx     set line height to  n /216-inch for next LF (0aH)
ESC 2      1b 32        execute variable-height line feed (See ESC A) also
6 LPI: set 1/6" line height (if no prior ESC 2)
ESC A  n   1b 41 xx     select a line height of  n /72-inch.
(this is a one-shot linefeed triggered by ESC 2)

ESC C  n   1b 43 xx     set lines per page to n (0-7fH)
ESC N  n   1b 4e xx     set skip perforation to  n  lines

Miscellaneous
ESC 8      1b 38        ignore end of paper

ESC U  0   1b 55 00     start bi-directional printing

ESC B  n..0             set VERTICAL TAB STOPS (send ESC B followed by a
1b 42 xx..00    series of binary values, ending in a byte of 0)
ESC D  n..0             set HORIZONTAL TAB STOPS (send ESC D followed by a
1b 44 xx..00    series of binary values, ending in a byte of 0)
