Set MSB to 0 ESC =
Sets the MSB (most significant bit) of all following data to zero. Some computers always set the MSB to
one, causing all characters to print in italic mode. This escape sequence can overcome the problem. The
problem can also be avoided by setting “Data Bits” to “7” in the interface setup menu.
Escape Sequence: ESC =
Hexadecimal: 1B 3D
Set MSB to 1 ESC >
Sets the MSB (most significant bit) of all following data to one. This escape sequence allows the eighth bit to
be turned on, even if the computer and printer are connected via a 7-bit I/O interface. The eighth bit may be
useful for 8-pin graphics data, or for accessing italic characters.
Escape Sequence: ESC >
Hexadecimal: 1B 3E
Cancel MSB Control ESC #
Cancels the MSB (most significant bit) control set by ESC = or ESC >. This causes the eighth data bit sent
from the host computer to be accepted as is.
Escape Sequence: ESC #
Hexadecimal: 1B 23
Deselect Printer DC3
(or) XOFF
Deselects the printer. Use of this command is discouraged, because the printer will remain offline until an
operator presses the ONLINE button on the control panel.

Character Size
The FormsPro, FormsMaster and PrintMaster series printers are capable of supporting 10, 12, 13.3, 15,
16.7, 17.14, and 20 cpi, but most emulations support only a subset of these. Epson emulation supports 10,
12, 15, 17.14, and 20 cpi via software, but does not support 13.3 or 16.7 cpi. Every emulation supports 10
cpi, and we consider this to be the default character pitch. When you use the control panel to change the
“Characters/Inch” value in the forms menu, you are actually changing the default character pitch. When the
printer is turned on (or reset), it will use this character pitch. You can even use a pitch that is not supported
by your emulation, such as 13.3 cpi with Epson emulation. You can override this pitch selection via software,
by sending an escape sequence. This selects a user specified non-default pitch. For example, in Epson
emulation, sending ESC M will select 12 cpi. Sending ESC P will re-select 10 cpi, and thus re-select the
default character pitch that was selected in the form setup.
