Extended Printer Control
The POSjet
®
1500 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.
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) Reset cartridge Ink Status
2) Print current configuration
3) Print current log totals
4) Print current alignment values
NOTE: All of these commands follow the ESC ~ or ESC y 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.
Function Reset Cartridge Ink Status
ASCII [ESC] ~ H <n>
Hexadecimal 1BH 7EH 48H <n>
Decimal <27> <126> <72> <n>
Description This command allows the host system to operate the cartridge change operation under program
control and provides a means to unconditionally inform the printer that the cartridge has been
changed. If <n> = 1 or <1> the black or left cartridge status is reset. In <n> = 2 or <2> the color
or right cartridge is reset.
Note It must be noted that this command will reset the ink status even if the cartridge has not been
replaced. If this occurs, the ink low warning will not be accurate.
