Chapter 2 — Sending ESim Commands to the Printer
12 ESim for the PC4 and PF8 Printers Programmer’s Reference Manual
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 “Commands List” on page 3.
The printer enters Direct mode after it is turned on. Exiting other
modes may also return the printer to Direct mode.
Print Mode
Use print mode 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
button. The printer switches to Print mode.
• From Print Pause mode, execute the ^C command to return to
Print mode.
To exit Print Mode
