Transfer of user data
The transfer of MSR data is archived by adding an STX... ETX sequence to the
respective CSI command:
CSI ... I F STX...ETX
Reaction to incorrect parameters
Normally an additional command is ignored if non- decimal parameters or para-
meters exceeding the specified value range are transferred. This also applies if
the set format height is infringed by the vertical positioning. Exceptions to these
rules are given with the description of the appropriate command, as appropriate.
Responses
Responses of the document printer can be grouped as follows:
– Requested data response
– Global printer status (GPS)
– Special printer message (SPM).
