21.10 Sending Data to a Printer with SFB 16 "PRINT"
Description
SFB 16 "PRINT" sends data and a formatting instruction to a remote printer, for
example, via the CP 441.
When there is a rising edge at control input REQ, the format description (FORMAT)
and the data (SD_i) are sent to the printer selected with ID and PRN_NR.
If you do not use all four send areas, you must make sure that the first area is
described by the SD_1 parameter, the second area (if it exists) by the SD_2
parameter, the third area (if it exists) by SD_3.
Successful execution of the job is indicated by the DONE status parameter, errors
are indicated by the ERROR and STATUS parameters.
