							ENHorizontal Cursor Positioning (PCL Units) Command 6-7
Horizontal Cursor Positioning (PCL Units) 
Command 
This Horizontal Cursor Positioning command moves the cursor to a 
new position along the horizontal axis.
? * p # X
#  =   Number of PCL Units
Default =NA
Range =0 - logical page right bound
A value field (#) with a plus sign (+) indicates the new position is to 
the right of and relative to the current cursor position; a minus sign (–) 
indicates the new position is to the left of and relative to the current 
cursor position. No sign indicates an absolute distance which is 
referenced from the left edge of the logical page. The left most 
position is 0 and the right most position is the right bound of the 
logical page.
If a request is made for a location outside the printer’s logical page, 
the current active position (CAP) is moved to the appropriate logical 
page limit.
NoteThe current unit size used in PCL Unit moves is determined by the 
value specified in the Unit of Measure command. If no other value is 
specified, the number of units-per-inch for PCL Unit moves is one unit 
equals 1/300 inch.

Horizontal Cursor Positioning Control Codes 
Four control codes can be used to position the cursor horizontally on 
the current line. These control codes are explained below.
NoteThe distance which the cursor is moved by the Space (SP), 
Backspace (BS), and Horizontal Tab (HT) control codes is defined by 
the current HMI value. The current unit of measure setting affects how 
HMI values are rounded. For example, if the unit of measure is set to 
96 (one PCL Unit = 1/96 inch), then the HMI is rounded to the nearest 
1/96 inch. If the unit of measure is set to 300 (one PCL Unit = 1/300 
inch), the HMI is rounded to the nearest 1/300 inch.
CR - Carriage Return 
Moves the current active position (CAP) to the left margin on the 
current line. (Refer to “Line Termination Command” later in this 
chapter.)
SP - Space 
Moves the current active position (CAP) to the right by one column 
position. Space may be a printable character or a control code. If a 
character is defined for the Space code, Space is printable; 
otherwise, it is a control code. For proportionally spaced fonts, a 
Space control code moves the cursor by the current HMI value; 
however, a printable space moves the cursor the width of the 
character. For fixed pitch fonts, a space, whether control code or 
printable, moves the cursor according to the HMI value. 
						

							ENHorizontal Cursor Positioning Control Codes 6-9
BS - Backspace 
Moves the current active position (CAP) left a distance equal to the 
width of the last printed symbol or space. If the active position is 
already at the left margin, no action is taken. If the cursor is currently 
beyond the right margin, BS positions the cursor just to the left of the 
right margin. When using fixed pitch fonts, the Backspace distance is 
defined by the current print pitch (HMI setting).
When using proportionally-spaced fonts, a single Backspace moves 
back to center the overstrike character. After printing the overstriking 
character, the cursor returns to its position prior to the Backspace. 
Multiple backspaces each move back the distance of the last printed 
symbol or space. For example, if “world” was printed with a 
proportional font and then 5 backspaces were performed, the 
distance moved back would be five times the width of the “d.”
HT - Horizontal Tab   
Moves the current active position (CAP) to the next tab stop on the 
current line. The tab stops are at the left margin and every 8th column 
between the left margin and the right bound of the logical page. If the 
new horizontal position crosses the right margin, the new horizontal 
position is set to the right margin. If the current HMI value is 0, the 
command is ignored.     
						

							6-10   Cursor PositioningEN
Vertical Cursor Positioning (Rows) Command 
This Ver tical Cursor Positioning command moves the cursor to a new 
line in the same column position.
? & a # R
#  =   Number of Rows
Default =NA
Range =–32767 to 32767 (valid to 4 decimal places)
A value field (#) with a plus sign (+) indicates the new position is 
downward from and relative to the current cursor position; a minus 
sign (–) indicates the new position is upward from and relative to the 
current cursor position. No sign indicates the new position is absolute 
from the top margin. The top position, defined by the top margin, is 0 
and the bottom position is determined by the bottom of the logical 
page.
NoteSince the top margin can be changed using a printer command, the 
physical location of the point (0,0) may change. This affects the cursor 
position on the page.
If a request is made for a location outside the printer’s logical page, 
the current active position (CAP) is moved to the appropriate logical 
page limit. 
						

							ENVertical Cursor Positioning (Decipoints) Command 6-11
Vertical Cursor Positioning (Decipoints) 
Command      
This Ver tical Cursor Positioning command moves the cursor to a new 
position along the vertical axis.
? & a # V
#  =   Number of Decipoints (1/720 inch)
Default =NA
Range = –32767 to 32767 (rounded to the first decimal place)
A value field (#) with a plus sign (+) indicates the new position is 
downward from and relative to the current cursor position; a minus 
sign (–) indicates the new position is upward from and relative to the 
current cursor position. No sign indicates an absolute distance from 
the top margin. The top position, defined by the top margin, is 0 and 
the bottom position is determined by the bottom of the logical page.
NoteSince the top margin can be changed using a printer command, the 
physical location of the point (0,0) may change. This affects the cursor 
position on the page.
If a request is made for a location outside the printer’s logical page, 
the current active position (CAP) is moved to the appropriate logical 
page limit.

Vertical Cursor Positioning (PCL Units) Command      
This Ver tical Cursor Positioning command moves the cursor to a new 
position along the vertical axis.
? * p # Y
#  =   Number of PCL Units
Default =NA
Range = –32767 to 32767
A value field (#) with a plus sign (+) indicates the new position is 
downward from and relative to the current cursor position; a minus 
sign (–) indicates the new position is upward from and relative to the 
current cursor position. No sign indicates an absolute distance from 
the top margin. The top position, defined by the top margin, is 0 and 
the bottom position is determined by the bottom of the logical page.
NoteSince the top margin can be changed using a printer command, the 
physical location of the point (0,0) may change. This affects the cursor 
position on the page.
If a request is made for a location outside the printer’s logical page, 
the current active position (CAP) is moved to the appropriate logical 
page limit.
NoteThe current unit size used in PCL Unit moves is determined by the 
value specified in the Unit of Measure command. If no other value is 
specified, the number of units-per-inch for PCL unit moves is one unit 
equals 1/300 inch. 
						

							ENHalf-Line Feed Command 6-13
Half-Line Feed Command     
The Half-Line Feed command moves the cursor to the same 
character position one half-line down. The distance moved for a 
Half-Line Feed is one-half of the current line spacing (defined by the 
last VMI or line spacing setting).
? =       
Vertical Cursor Positioning Control Codes 
Two control codes can be used to position the cursor vertically. These 
control codes are explained below.
LF - Line Feed
Advances the current active position (CAP) to the same horizontal 
position on the next line. The distance to the next line is defined by 
the current line spacing (defined by the last VMI or line spacing 
setting). (Refer to “Line Termination Command” later in this chapter.)
FF - Form Feed
Advances the current active position (CAP) to the same horizontal 
position at the top of the text area on the next page. (Refer to “Line 
Termination Command” later in this chapter.)       
						

							6-14   Cursor PositioningEN
Line Termination Command 
The Line Termination command controls the way the printer interprets 
CR, LF, and FF control characters. All CR, LF and FF control 
characters received after the Line Termination Command are 
interpreted as shown below.
? & k # G 
#  =   0- CR=CR; LF=LF; FF=FF
   1 - CR=CR-LF; LF=LF; FF=FF
   2 - CR=CR; LF=CR-LF; FF=CR-FF
   3 - CR=CR-LF; LF=CR-LF; FF=CR-FF
Default =0
Range =0-3
For example, if a value field of 1 is sent, the printer interprets each 
Carriage Return (CR) received as a Carriage Return (CR) and Line 
Feed (LF) control code. A Line Feed or Form Feed would be sent 
as is.
If a value of 3 is sent, the printer interprets each Carriage Return (CR) 
received as a Carriage Return (CR) and Line Feed (LF); it interprets 
each Line Feed (LF) received as a Carriage Return (CR) and Line 
Feed (LF); and it interprets each Form Feed (FF) received as a 
Carriage Return (CR) and Form Feed (FF).       
						

							ENPush/Pop Cursor Position Command 6-15
Push/Pop Cursor Position Command 
The Push/Pop Cursor Position command allows the current cursor 
position to be stored and recalled.
? & f # S
#  =   0  - Push (Store cursor position)
     1 - Pop (Recall a cursor position)
Default =0
Range =0, 1 (Values outside range are ignored)
A value field of 0 pushes the cursor position onto the stack, leaving 
the current position unaffected. A value field of 1 pops the position 
from the stack, restoring it as the current cursor position.
NoteThe last item pushed is the first item popped.
Twenty positions may be pushed. If you try to save more than 
20 positions, the command is ignored. If you try to restore more 
positions than were pushed, the command is ignored. A printer reset 
restores the current active position stack to the top (all saved 
positions are discarded).
The positions stored in the stack are not changed with an orientation 
change. Therefore, the positions are relative to the top left corner of 
the current orientation. Also, a position pushed in one orientation and 
popped in another can result in a position that is outside the logical 
page. If the position popped is outside the current logical page, the 
position is moved to the appropriate logical page limit.
