Chapter 7 — Commands
ESim for the PC4 and PF8 Printer Programmer’s Reference Manual 129
Command must end with <CR> or <LF> to be correctly
executed.
The printer replies to the host via serial port in one of the
following formats:
1 If no error code is available (normal case):
00<CR><LF>
00 = Status code OK
2 If only one error code is available:
XX<CR><LF>
XX = Error or status code
3 If more error or status codes are available:
XX,YY,ZZ..<CR><LF>
XX YY ZZ.. = Error or status codes.
An ^ee command cannot be performed:
• during downloading of images, fonts, or forms.
• inside a variable input (?), or inside a string area (“”).
• when the input data buffer is full (> 8000 bytes).
At position error-waiting-recovering, the command ^ee must be
sent into the printer via the RS-232 or USB interface to get an
error report.
Note: An error report has higher priority than other commands
and is processed directly, both in position of normal command
input and in position of any error recovery.
