The Output P1 And P2 Instruction, Op - HP 7470A Interfacing And Programming Manual

Negative parameters greater than or equal to -32 768will be set to zero.
Parameters outside the maximum plotting area (determined by the set­
ting of the paper switch) but less than 32 767 will be set to the limits of
the plotting area. Parameters less than -32 768 or greater than 32 767
will cause error 3 and the coordinates of P1 and P2 will not change.
An IP command without parameters will default P1 and P2 to the
values 250, 279, 10 250 , 7479 regardless of the paper switch setting.
Upon receipt of a valid IP command, bit position 1 of the output status
word is set true (1). \
Upon power on, front-panel reset, or execution of an IN or DF com­
mand, the character size is set relative (SR) to the locations of P1 and
P2. Unless an SI command has been entered as part of the program,
the character size will be directly affected by the IP command.
The following HP—GL command relocates the scaling points P1 and P2
to the positions shown in the figure.
"IF 3ooo,2ooo,5ooo,50oo;"
P2
° (5ooo,5ooo)
P1
(3000,2000)
