Updating instructions for printers with a current firmware version of 4.05 and above:
1.Identify the desired firmware revision from the Datamax FTP site at ftp://ftp.datamaxcorp.com and download the desired version on to your computer’s hard drive or a floppy disk.
2.With the printer’s power turned ‘on’, the printer is now ready to accept the new firmware data. Using the DOS copy command enter:
copy filename.dlf lpt1/b
Note: Other programs (such as
The Paused Indicator blinks during the download. After a successful download, the printer will illuminate the Paused Indicator steady. The printer will write to Flash memory after all data is received, and the checksum and other data are validated. Then a ‘cold reset’ will occur. (When connected through the serial port, the printer will also transmit an ‘R’ when complete.) Print a Configuration Label (<STX>Z) to verify the new firmware version.
Conversely, if the download was unsuccessful, the ‘Fault’ Indicator will illuminate and the printer will ‘warm reset’. (When connected through the serial port, the printer will also transmit a ‘T’ when complete.) The previous firmware programming will not be affected, unless substantial firmware data structure changes have occurred. If the printer fails to warm reset, it may be necessary to toggle power ‘off’ and ‘on’, or simultaneously pres s and release PAUSE and CANCEL Buttons.
Note: The printer will wait forever for the specified number of bytes to be transmitted by the host. If a communications error occurs and the host transmission is complete. The host may transmit fill data or an <SOH># to ‘warm reset’ the printer.
If the download fails, try
