How to Copy/Upgrade the Printer Base Code via Parallel Cable
|Lexmark T640||Lexmark T642||Lexmark T644|
Any user can upgrade the printer's base code. The only requirements are a computer, the code file(s) needed, and a way of connecting the computer to the printer. However, it is strongly recommended that the person performing the upgrade be experienced with Windows and MS DOS operating systems and networking.
If you cannot copy the base code file to the printer using a parallel connection, you can also try upgrading the base code using a USB connection or via the network through an ftp command.
