A–24 Bar Codes
Subset A – Subset A operates in the manual mode only. Subset A data
characters include mostly normal printable ASCII characters which require
no subset switching and can be entered directly. For example, the data
ABC123 in subset A is input in the bar code command as:
ESC%0>7ABC123ESC%@. Switching to another subset will not generate a
shorter bar code.
You can generate non–printable control characters in subset A by:
1) using the subset B lowercase character equivalent from Table A–3
( ‘ through ~), which map to NUL through RS; or
2) using the subset switch characters (>1 through >8, or >SP through >/)
from the Alternate column of Table A–3.
