Notes:
1. The host should set the limits of the presentation surface if the default or
previous values are not acceptable.
2. The operator should align the physical paper so that it matches the logical
presentation surface.
Also created with this surface is a pair of numbers (CPL and CPP) which specify
the line number and column number where the next graphic will be printed. These
internal values are the logical position on the presentation surface.
The variable parameters have default values which are established when the printer
is initialized. The standard power-on defaults are:
TOF Operator panel setting
PL Operator panel setting
CPI Operator panel setting
LPI Operator panel setting
LM 0 inches (Column 1)
RM Operator panel setting
SOP Operator panel setting
