MICR FONT NOTE – The E-13B and CMC7 Fonts are 8 characters per inch. To position
correctly at an exact 8 characters per inch, the printer must be set to an internal Unit of Mea-
sure of 600 DPI or greater or must have a horizontal motion index command at 8 CPI be
issued after the font call. This is true even if the base printer is at 600 DPI. The default charac-
ter positioning is at 300 DPI and 8 into 300 is 37.5 pixels. The printer will either round down to
37 or up to 38 pixels causing characters to creep. To resolve this there are multiple options.
1. If you are using a printer driver that is set to 600 DPI, the printer data stream should include
a Unit of Measure PCL command set to 600. The command is <ESC>&u600D
2. If the application controls the printer data stream, add the Unit of Measure command early
in the data stream. The command also affects X & Y positioning commands. Add
<ESC>&u600D
3. After calling the E-13B MICR font, issue a HMI (Horizontal Motion Index) command set to 8
characters per inch. The command must be included with every E-13B MICR font call
using either the Selection String or ID call. The command string is:
<ESC>(10O<ESC>(s0p8h8v0s7b360T<ESC>&k15H font data The Selection String
<ESC>(30802X<ESC>&k15H font data The ID Call
See Font Mapping Appendix pages for specific character set data for each font.
PJL INFO MICR COMMAND
The ST Secure MICR Printer supports an optional custom bi-directional PJL Inquiry
Command. The command provides printer information and cartridge information for network
management. The command format is; @PJL INFO MICR
The command should be sent with UEL (Universal Exit Language) commands. Example:
<ESC>%-12345X UEL
@PJL INFO MICR INFO MICR Command
<ESC>%-12345X UEL
The following data is returned
@PJL INFO MICR
PRINTER STATE = READY
= BUSY
= NOT READY
SERIAL NUMBER = XXXXXXXX
PAGECOUNT = 123456
CARTRIDGE TYPE = NORMAL
= MICR
