01H–09H, 0EH, 0FH, 1BH — Host Mode Control
The Host Mode Control feature allows you to change print/plot mode on a
line–by–line basis without interrupting printer operation. Without this
feature, print/plot mode is determined by the setting of Configuration Option
30, which is loaded when the power is turned on, or manually changed when
using the control panel switches.
You can change modes on the 150B/L150B printers using host mode control
by embedding the mode change control code sequence in the data stream.
Control code sequences are interpreted according to the configuration
options resident in printer firmware, and the printer output is modified
accordingly.
Host Mode Control Feature Selection
Data stored at Configuration Option 20 determines whether the host mode
control feature is enabled or disabled and what the command sequence
recognition programming standard is. You can select either 20.1, P–Series
programming standards, or 20.2, ANSI programming standards, (refer to
Chapter 4, Configuration).
With Configuration Option 20.1
Configuration Option 20.1 enables host mode control using the P–Series
programming standard. Valid control code sequence headers (beginning
characters) are defined by option numbers contained in Configurations 31
through 41. Valid P–Series control code headers and their associated
configuration options are listed in Table 7–7. Print mode change control code
sequences must begin with the selected P–Series header.
With Configuration Option 20.2
Configuration Option 20.2 selects host mode control using the ANSI
programming standard. This standard requires all print mode change control
code sequences to begin with the Esc header (1BH).
NOTE: When Configuration Option 20.2 is selected, Electronic Vertical
Format Unit (EVFU) channel 12 (Vertical Tab 1BH) will not
operate.
