CSI Pn1 ; Pn2 R
Values of Pn (up to three digits) are defined in Table 7–18. Printer status
codes are reported in pairs: a generic error code first, then a specific error
code.
A hardware failure consists of any errors listed in “Self–test error messages”
and “Font Checksum Errors found at Initialization.”
1. Communication failures are usually attributed to parity errors, framing
errors, or receipt of an erroneous character.
2. Failures designated as events are reset only when an extended report is
sent. If set for solicited reports, the events are reset only after the report
is requested and reported. If set for unsolicited reports, the report is
immediately sent and the event cleared.
3. RIS and DECSTR reset any event not reported.
4. All non–events are not latched, but continuously reflect the current state
of the relevant parameter.
