The current unit of measure setting affects all PCL Unit moves, 
horizontal and vertical rectangle size, bitmap and scalable font 
metrics (how the cursor moves after printing a character). The Unit of 
Measure command does not affect the interpretation of binary raster 
data (bitmap fonts, raster graphics or patterns).
Once the units of measure is changed, it stays in effect until another 
is selected or the printer is reset. A control panel or ? E reset returns 
the...

ENUnit of Measure Command 4-15 Figure 4-6 Cursor Moves at Different Unit of Measure Settings 
The printer’s physical dot size has no direct bearing on the size of 
PCL Units used in cursor movements. In addition, PCL Units are not 
affected by the current control panel or PJL resolution setting.
NoteIf no other unit of measure value has been specified, then the default 
is one Unit equals 1/300 inch. In this case, a cursor movement of 
450 Units moves the cursor 1.5 inches, whether printed at 300 or 
600...
