Figure 10. P-Series Plot Data Byte Format
Plot Data Line Format
A plot data line may contain the following plot data bytes: When using 132 
column paper, the maximum bytes are 132 for a horizontal dot density of 60 
dpi or 198 bytes for a horizontal dot density of 90 dpi. If Auto Line Feed is 
disabled, any bytes over the maximum are lost. If the maximum is exceeded 
and Auto Line Feed is enabled, a Line Feed (LF) is forced and the remaining 
plot data is printed as text on the next line.
The plot mode control code may occur anywhere in the line prior to the line 
terminator, but plot speed may decrease if it is not at the beginning of the line.
