Electronic Journal
The iTherm
®
280 has the capability to store electronic journal
9
data in flash memory.
There are two ways entries can be made into the electronic journal. The first is by
selecting the journal station. The second is by requesting that print data be placed into
the electronic journal.
Before the electronic journal can be used, it must be configured and initialized.
Configuring the Electronic Journal
The iTherm
®
280 has about
10
1024K bytes of flash that can be assigned to the electronic
journal or to extended user store. The 1024K is segmented in 64K segments, which may
be assigned to either to electronic journal or extended user store. That is you can assign
2 segments or 128K to the electronic journal and the remaining segments will be
assigned to extended user store.
When electronic journal is in use, you can not reconfigure the configuration of the
extended flash memory. If you want to reconfigure the flash, the electronic journal must
be erased. To erase the electronic journal you must know the password that was
assigned when it was initialized. When printers are initially configured by TransAct, the
extended flash is erased and partitioned but not initialized. Before you use the electronic
journal you must initialize it.
CAUTION: You can use the extended user store without initializing the
electronic journal. If any data has been stored in the extended user store,
it will be lost if the extended flash is repartitioned.
CAUTION: The printer does not stop if the electronic journal runs out of
memory. If the printer were to stop there would be no way for the host to
print and clear the journal. The host system should monitor the Journal
with the [ENQ]<25> command. This command will return the electronic
journal status and report how much memory is remaining (See page 147).
When the free electronic journal space is less than a predetermined
amount, the journal should be printed or retrieved and then reinitialized.
Electronic Journal Security
Electronic journal security is provided by applying a password to the erase feature of the
electronic journal. Additionally, there is a factory set configuration that disables the ability
for the operator to print the journal through the keypad.
It is possible to assign a blank password to the electronic journal. If this is done either
through the keypad or by host control, the manual print mode will be allowed to erase
and reinitialize the journal.

It must be noted that the iTherm
®
280 does not maintain the current time or date. If a journal
entry is to contain the time and/or date, the host system must transfer this as printable text.

The amount of free flash depends on the version of code installed and the amount of flash used
for enhanced language support.
