4.1. 

Start Raster Transfer 

Command 

ESC*r#A (27)(42)(114)#(65)  <1Bh><2Ah><72h>#<41h> 

#  = 0 * 

Prints the image from the left edge of the logical page. 

= 1   

Prints the image from the current cursor position. 

= 2 

Executes scaling.  Prints the image from the left edge of the logical page. 

= 3 

Executes scaling.  Prints the images from the current cursor position. 

* Default value = 0 

• 

This command signals the start of the transfer of raster image data to the printer. 

• 

The transfer of raster data to the printer continues until either an 

End Raster Transfer

 command is sent or a 

command other than 

Send Raster Data

, 

Set Compression Mode

 or 

Y-Offset

 is sent. 

• 

The source width and height are set by the 

Set Raster Area Width

 (

ESC*r#S

) and 

Set Raster Area Height

(

ESC*r#T

) commands.  When the # value is 2 or 3, the data with these source width/height values is 

enlarged or reduced to the width and height set by the 

Set Destination Raster Width

 and 

Set Destination 

Raster Height

 commands.  (Refer to the following sections.) 

4.2. 

Set Destination Raster Width 

Command 

ESC*t#H (27)(42)(116)#(72)  <1Bh><2Ah><74h>#<48h> 

Range = 0 ~ 32767 (number of decipoints in 1/720”) 
Default value = 0 

• 

If value 2 or 3 is sent with the 

Start Raster Transfer

 command and graphic scaling is set, this command sets 

the destination width. 

• 

Values outside the range are invalid. 

• 

If the setting is 0 or is omitted, this command uses the same width as the source width. 

• 

If the specified width is wider than the page, drawings are clipped by the right physical page boundary.  The 

scaling factor is dealt with correctly. 

4.3. 

Set Destination Raster Height 

Command 

ESC*t#V (27)(42)(116)#(86)  <1Bh><2Ah><70h>#<56h> 

Range = 0 ~ 32767 (number of decipoints in 1/720”) 
Default value = 0 

• 

If value 2 or 3 is sent with the 

Start Raster Transfer

 command and graphic scaling is set, this command sets 

the destination height. 

• 

Values outside the range are invalid. 

• 

If the setting is 0 or is omitted,  this command uses the same  height as the source height. 

• 

If the specified height is longer than the page, drawings are clipped by the bottom of physical page boundary.  

The scaling factor is dealt with correctly.
