DSR
Chapter 8. PPL3 Plus Emulation
The number of DSR requests the printer can process is limited only
by the transmission time of each report.
Error Handling
If Ps has a value other than those shown, the printer ignores the
entire command.
Device Status Report: Reports error status. The printer sends this
report:
▪ In response to an error condition (if unsolicited reports are
enabled)
▪ In response to a Printer Status Request (DSR) with Ps = 0, 5, ?2,
or ?3.
Unsolicited status reports are sent upon completion of the current
page.

Extended Report Description
Each Pn value is an error code of up to three digits. Error codes occur
in pairs: a generic code, followed by a specific code.
CSI ? 36 ? 216 n
CSI ? 26 ? 212 n
Notes
If unsolicited reports are enabled, errors are reported as they occur.
If no errors occurred, the printer returns a generic "no error" code.
This code varies depending on the printer configuration.
If an event error occurs when unsolicited reports are disabled, the
event is stored and reported on the next request. If a state error
occurs when unsolicited reports are disabled, an error report is
generated on the next request only if the error condition still exists -
for example, the cover is open or the printer is off line.
If enabled, the printer transmits a report before going offline in
response to a serious engine error.
