• Coordinate values for P1
• You can set P1 and P2 to be anywhere that the range of allowable coordinates permits.
parts of resulting images that lie within the effective window will be printed.
• The default location of P1 is the lower left corner and P2 is the upper right corner of the PCL picture frame.
• Using this instruction without a parameter field initializes the scaling points(P1,P2) to the default location.

• If P2x and P2y are omitted P2 is set to be in the same position relative to P1 that it was before the command
was invoked.
• The IP command remains in effect until another IP command,

• The coordinate values are percentages relative to the bottom left and top right hand corners of the picture
frame.
• Coordinate values for P1x, P1y, P2x, and P2y are treated as clamped real numbers.
• Using this instruction without parameters sets the scaling points (P1, P2) to their initial positions, the bottom
left and top right hand corners of the picture frame.
• If P2x and P2y are omitted P2 is set to be in the same position relative to P1 that it was before the command
was invoked.
• You can set P1 and P2 to be anywhere that the range of allowable coordinates permits.
