2.5.1 Feature 28 - PRINT INHIBIT
In certain applications, the user may wish to selectively enable or disable the
printing of data received by the printer. This capability may be selected by
enabling Feature 28. When enabled, a CONTROL S received by the printer via
the communications line will inhibit the printing of received data. A CONTROL
Q received via the communications line signals the printer to resume printing
received data.
To disable the print inhibit capability, enter setup mode, advance to Feature 28,
and press Clear key. A “0” will be shown in the right-most column of the display.
To enable the print inhibit capability, press the Set key. A “1” will then be shown.
2.5.2 Feature 29 - EXPANDED CHARACTER PRINTING
The printer is capable of printing expanded characters at 5, 6, 6.6,7.5, 8, and

certain portions of the text such as titles or headings.
This feature determines the capability to select between character sizes and not
the actual selection of the character itself. The selection of normal or expanded
print is determined by a CONTROL Code. A CONTROL N (shift-out) selects
expanded print when Feature 29 is enabled. A CONTROL O (shift-in) selects
normal print when Feature 29 is enabled. If Feature 29 is disabled, expanded
print caimot be selected. If Feature 41 is enabled, CONTROL N and
CONTROL O are used to select the primary and secondary character set (printer
mode only).
NOTE
If Feature 45 is enabled, the print will automatically revert
to normal size at the end of a line.
