Description
This command opens a downloaded file and establishes the file handle. Up to two file handles are
supported, thus only up to two files can be opened simultaneously. The file to be opened should be
downloaded prior to using this command. When opening a file, the firmware will search automatically
to see if the file exists in the on board flash memory or extended memory card. *Since V6.37 EZ, if the
file doesn’t exist, the printer will create this file in the onboard FLASH.
Syntax
