Zanasi has come out with a new series of printer that is not backwards compatible with our existing Zanasi Driver.

The new series of printer have models in the Z4xx range with xx being a 2-digit number. For example, Z402.

They do supply a special modification of sorts, a sniffer that looks for the text in the print command and inserts it in a predefined message format on the printer. For example, "$00WT000ATEST123{space}{space}[CR]" is a valid print command. TEST123 will be extracted and be filled into the message to be printed.

We have taken the existing Zanasi print driver and modified it. A new entry, "Simple Zanasi Z4xx" has been added to the list of part printers. When this entry is selected, the existing print driver will be used with much of its code disabled. All print text will be concatenated and sent in a command that is formatted like the example. No version information or print buffers will be read from the printer as those commands are not supported in the printer.

The existing driver stripped off the message formatting when displaying the print message in the diagnostic window. When this new entry is selected, since the command format is so specific, it is displayed with the text to provide confidence that we are using the expected command format.
