CHAPTER 3 PCL5C - 13 

4.4.

Set Scale Algorithm 

Command 

ESC*t#K (27)(42)(116)#(75)  <1Bh><2Ah><70h>#<4Bh> 

#  = 0 * 

Takes the lighter overlying dots when reducing. 

  = 1   

Takes the darker overlying dots when reducing. 

* Default value = 0 



This command sets which algorithm the data is reduced by. 



Any combinations, such as vertical only, horizontal only or vertical and horizontal are allowed to be reduced.   
If the setting is vertical only or horizontal only, this command affects the set direction. 



This command should be used after sending the 

Start Raster Transfer

 command after setting the scaling 

(ESC*r2A or ESC*r3A). 

4.5.

Send Raster Data by Plane 

Command 

ESC*b#V [data] (27)(42)(98)#(87)  <1Bh><2Ah><62h>#<56h> 

Range = 0 ~ 32767 
Default value = N/A 



This command sends a plane of data to the printer and goes ahead to the next plane (not to the next row).   



The # value represents the number of data bytes to be sent.    The number of planes per row is specified by 
the 

Set Simple Color

 command or the 

Set PCL Color

 command, depending on which color mode is used.   

The first plane sent represents the least significant bit in the pixel. 



Since this command does not affect the cursor position, it cannot be used for the last plane or for single-
plane rows.  Only the 

ESC*b#W

 command can progress the cursor to the next row. 



The amount of data sent varies depending on the plane, and it is separate from the raster width.    When the 
data sent is shorter than the raster width, the data which was not filled within the specified raster width is 
cleared to 0.    Empty planes can be sent when the # value is 0. 

4.6.

Enter HP-GL/2 Mode 

Command 

ESC%#B (27)(37)#(66)  <1Bh><2Ah><25h>#<4Ah> 

#  = 0 * 

Position the cursor at the previous HP-GL/2 cursor position. 

  = 1 

Leave the cursor at its current PCL position. 

  = 2 

Use current PCL coordinate system and previous HP-GL/2 pen position 

  = 3 

Use PCL dot coordinate system and the current cursor position 

Range = 0 ~ 3 
* Default value = 0 



Immediately after the printer receives this command, it switches to HP-GL/2 mode, interpreting commands 
as HP-GL/2 commands until it receives an 

Enter PCL Mode

,

Reset 

or

 UEL

 command, or until the printer is 

turned off and on. 



The # value specifies the cursor position once HP-GL/2 mode is entered.    Each value performs the 
following functions; 

•  # = 0:

The cursor is positioned at the previous HP-GL/2 cursor position.    If this is the first time you 
have switched to HP-GL/2 mode since switching the printer on, the cursor is placed at the origin 
of the HP-GL/2 graphics windows. 

•  # = 1:

The cursor remains at its current position. 

•  # = 2:

The PCL coordinate system is used when entering into HP-GL/2 mode from PCL mode. The 
HP-GL/2 cursor position uses the previous HP-GL/2 position.    It is separate from the P1 and P2 
positions. 

•  # = 3:

The PCL coordinate system is used when entering into HP-GL/2 mode from PCL mode .    The 
PCL cursor position is used instead of the HP-GL/2 cursor position.    It is separate from the P1 
and P2 positions.
