usb.host.read_list

This command scans the mounted usb mass storage device for non-user-restricted files and displays the files in a list.

Setvar

To scan the mounted usb mass storage device for non-user-restricted files and displays the files in a list:
! U1 setvar "usb.host.read_list" "value"
Values
  • "fill_store"
    The printer creates a list of all of the top-level files that are readable on a connected mass storage device. (
    .ZPL
    and
    .XML
    files)
  • "store"
    The printer copies the current file (the file listed on the display) or all eligible files if
    SELECT ALL
    is displayed from the USB mass storage device to the printer’s
    E:
    drive.
    "store"
    does an exact byte-for-byte copy of the file being stored. ZPL files that are transferred to the printer using the “store” command are NOT prepared to be used with a recall format command (^XF). See XREF Character Substitution (in Mirror) for the modifications necessary to prepare a ZPL file for use with ^XF. If the ZPL file contains a ^DF, the appropriate way to place it on the printer’s memory is to use the
    "print"
    command, below.

    SELECT ALL
