Enter - Intermec Janus 2020 User Manual

The JANUS 2020 reader uses Ctrl-P as the Command Override command;
however, the DOS printer redirection command (Ctrl-P) is also supported on
the reader. This dual purpose may cause some conflicts.
If you have Reader Services loaded and scan the bar code label <DLE>, the first
scan is interpreted as a reader command. The next <DLE> entered causes a
Ctrl-P to be entered into the expanded key buffer. DOS takes this Ctrl-P and
enables printer redirection.
If no printer is connected, all subsequent entries cause an error and the next
message is displayed:
Write fault error writing device PRN
Abort, Retry?
DOS shuts off the printer echo for the duration of the error, which allows it to
display the error. As long as the printer echo has been requested (by entering a
Ctrl-P), DOS turns the printer echo back on after the critical error is corrected.
To exit the critical error, press
and then press

Enter

Purpose: Enters the current data record or completes the entry of a command. If no data
exists, a null string is entered.
