Chapter 1 — Introducing ESim
ESim for the PC4 and PF8 Printer Programmer’s Reference Manual 5
Direct Mode
Direct mode is the main operating mode of the ESim protocol.
In Direct mode, various commands are available to set up and
reset the printer, store graphics and soft fonts, edit labels and
formats, request reports, clear the image buffer, and delete soft
fonts, forms, and graphics.
The Direct mode is also used for retrieving and printing
preprogrammed label formats. For a complete list of Direct mode
commands, see the “Command List” on page 11.
The printer enters Direct mode after it is turned on. Exiting
other modes may also return the printer to Direct mode.
Print Mode
Print mode is used to print labels, feed out blank media, and
control the optional cutter.
To enter Print mode
• From Direct mode, use the P, PA, or C command, or press the
Feed key. The printer switches to Print mode.
• From Print Pause mode, execute the ^C command to return
to Print mode.
To exit Print Mode
• Successfully complete a printing operation.
• Pause the printing operation with the ^A command.
For help, see “^A - Enter Pause Printing Mode” on page 126.
• Stop the printing operation with the ^B command. Note that
this also cancels any pending print jobs.
For help, see “^B - Break Batch Printing” on page 127.
Error Mode
Error mode is used for reporting and correcting various types of
errors. For more information see “Error Handling” on page 147.
The printer automatically switches to Error mode when an error
occurs. After recovering from an error, the indicator lamp
switches to green and the printer returns to the mode it was in
previous to the error.
