Electronic Journal
The Epic 880TM has the capability to store electronic journal8 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 Epic 880TM has about9 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 cannot 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 145). 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.
8It must be noted that the TransAct® Epic 880TM 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.
