[Description]
1. The “FS r+[n]” command is used to transmit a status parameter to the printer, which is sent back
as part of the response to a “Request printer status” command (“GS a+[01]
16
”).
2. This status parameter is specified by parameter [n].
3. The initial value for parameter [n] is [0]
10
.
4. The range of values for parameter [n] is [0]
10
≤ [n] ≤ [255]
10
.
5. As soon as the status parameter is transmitted back to the host in response to the “Request
printer status” command (“GS a+[01]
16
”), the value of the status parameter is reset to [0]
10
.
6. This parameter can also be transmitted using the End of Page command.
7. Typically, this command is used at the end of a print job to verify that the printout has been
completed successfully. First, FS r+[n} is sent to set the status parameter, then GS a+[01]
16
is
used to generate a printer status packet response. If the value of the returned status parameter
matches [n], then the print job has been successfully completed. If not, then the print job has
been lost.
8. It is also common to increment the value of [n] with each print job so that the host can identify
which print job was lost.
