Exception Reporting: Byte 2 of the EHC subcommand handles exception reporting. Bits 0, 1, and 7 of
this byte may be set to report or not report exceptions as defined below. If the exception has no Alternate
Exception Action or the printer is told not to take the Alternate Exception Action, the exception is always
reported.
● Bit 0: Report Undefined Character Check
When this bit is set to 1, an undefined data character in a Write Text, Write Graphics, or Write Bar Code
command causes the printer to report an error to the host program. When this bit is set to 0, the printer
does not report Undefined Character Check errors.
● Bit 1: Report Page Position Check
Printing occurs only where the physical medium and the logical page overlap. When bit 1 is set to 1, an
attempt to print outside the overlap of the logical page and the physical medium causes the printer to
report an error. If bit 1 is set to 0, the printer does not report Position Check errors.
● Bits 2-6: Reserved
● Bit 7: Report all other exceptions
