EPL Line Mode - Direct Thermal Printers only
Your direct thermal printer supports Line Mode printing. EPL Line Mode printing is designed to be
command compatible with EPL1 programming language used in early model LP2022 and LP2042 printers.
The Zebra 2800 series direct thermal printers also included Line Mode printer language support. The
Link-OS 4 inch Desktop continues Zebra’s support of Line Mode.
Line mode printing is ideal for basic retail (point of sale - POS), shipping, inventory, work flow control, and
general labeling. EPL printers with Line Mode, are versatile and are capable of printing a wide range media
and bar codes.
Line Mode printing only prints single lines the height of the largest element present in the line of text and
data - bar code, text, a logo or simple vertical lines. Line mode has many limitations due to the single line
of print: no fine element placement, no overlapping elements, and no horizontal (ladder) bar codes.
• Line Mode printer operation is entered by sending the printer the EPL
OEPL1 command. Refer to the
EPL Programmers Guide (Page Mode) or the EPL Line Mode Programmers Guide.
• Line Mode printer operation is exited by sending the printer the
escOEPL2 Line Mode command.
Refer to the EPL Line Mode Programmers Guide.
• With Line Mode active, ZPL and EPL (EPL2) Page Mode programming will be processed as Line
Mode programming and data.
• With the default ZPL and EPL (EPL2) Page Mode active, Line Mode programming will be processed
as ZPL and/or EPL programming and data.
• Verify printer programming modes by printing out a printer configuration.
