Summary of the CONFIG Command
The UPLOAD and DOWNLOAD command can be used for uploading and
downloading complete printer
configurations. If a customer needs to configure
50 printers identically, the customer needs only configure
one printer and
UPLOAD the configurations. The UPLOADed configurations may then be
DOWNLOADed
to other printers eliminating the necessity for the operator to
configure each printer manually.
The UPLOAD command will always place a header and footer into the
uploaded data. This header will be
the DOWNLOAD command followed by
the configuration number. The footer will be the DOWNLOAD END
command.
The operator should be aware that the UPLOAD and DOWNLOAD
commands use a secondary
copy of the menu structure which does not affect
the printer's active configuration. This allows the UPLOAD
and DOWNLOAD
commands to operate without affecting the printer's current configuration. If
the operator
intends to use one of the DOWNLOADed configurations, the
operator should reboot the printer to ensure
proper operation. This can be
accomplished by adding the RESET command as the last command in your
setup file. This is necessary because the printer caches the active
configuration. Rebooting the printer
ensures that the desired configuration is
correctly read from FLASH.
NOTE: While an upload or download is in progress, the Front Panel will be
unavailable.
Operation of the FILE_IO Command
When a file is opened for writing with the FILE_IO–CAPTURE;filename
command, the system will allocate
RAM for file control blocks and 1 Kbyte for
data. If the file already exists on the Flash File System and the
System > Flash File Edit > Overwrite Files menu is set to disable, a warning will
be displayed on the front
panel. After clearing the warning, the file data will be
printed. To overwrite the existing file, set the Overwrite
Files option to enable.
Due to the nature of writing to flash, any data intended to be stored
permanently in flash must first be
copied into RAM. As a result, the ability to
manipulate files in the Flash File System is dependent upon the
printer having
sufficient RAM. None of the captured file data will be committed to flash until
the entire file is
loaded. The PTX_SETUP parser will interpret the command
“FILE_IO–CAPTURE<lf>” as an end of file
marker. Receipt of the command
will cause all file data to be written to flash. The file system allocates RAM
for
temporary data storage in 1 Kbyte blocks. If at any time during the file
download the printer runs out of
RAM, a warning will be displayed on the front
panel and as much of the file as possible will be saved in
flash.
Three things can limit the ability to save a file: insufficient RAM, insufficient
Flash, and lack of empty file
system entries. Flash can only be written once
before it needs to be “optimized”. As a result, the maximum
file size is limited
to the largest unwritten block of Flash. If any of these problems occur, the
printer will
display an error message and will attempt to provide the operator
with a description of what steps to take to
correct the error. Normally, the
solution will involve optimizing the Flash File System. This can be
accomplished by selecting the System > Flash File Edit > Optimize & Reboot function.
