ZPL Configuration
Printer Memory Management and Related Status Reports
To help you manage printer resources, the printer supports a variety of format commands
to manage memory, transfer objects (between memory areas, import and export), object
naming, and provide various printer operating status reports. They are very similar to the
old DOS commands like DIR (directory listing) and DEL (delete file). The most common
reports are also part of the Zebra Setup Utility and ZebraDesigner ™ Windows driver.
It is recommended that a single command be processed within this type of format (form).A
single command is easily reused as a maintenance and development tool.
Many of the commands that transfer objects, manage and report on memory are control
(~) commands. They do not need the be within a format (form). They will be processed
immediately upon receipt by the printer whether in a format (form) or not.
ZPL Programming for Memory Management
ZPL has various printer memory locations that are used to run the printer, assemble the
print image, store formats (forms), graphics, fonts and configuration settings.
• ZPL treats Formats (Forms), Fonts, and Graphics like files; and memory locations
like disk drives in the DOS operating system environment:
• Memory Object Naming: Up to sixteen (16) alphanumeric characters followed
by a three (3) alphanumeric character file extension, for example:
123456789ABCDEF.TTF
Legacy ZPL printers with V60.13 firmware and earlier can only use the 8.3 file
name format verses today’s 16.3 file name format.
• Allows moving objects between memory locations and deleting objects.
• Supports DOS directory style file list reports as printouts or status to the host.
• Allows use of ‘wild cards’ (*) in file access
