The Ithaca
®
8000 printer has a number of Extended Control commands that allow an application
to better track and maintain the printer. These commands are in all emulations
16
.
The printer maintains a log of printer activity. This activity may be returned to the host with the
[ESC]~ T command. This command returns a ~T followed by four binary bits that make up a 32
bit unsigned integer. The description of the command below describes the format in full.
The printer also contains a number of commands that will force the printer to perform specific
functions to help maintain the printer or print information about the printer. The functions
available are:
1) Print Current Configuration
2) Print current log totals
Note: Each of these commands follow the ESC~ or ESCy format. Other
functions are performed by these basic commands. Do not attempt to use
any undocumented version of these commands. The extended diagnostics
commands may affect the print quality and performance of the printer. In
some cases, the commands may degrade the performance of the print
cartridge or mechanism.
