Then you may choose the appropriate PocketJet printer using either the ‘File’ pull-
down, or the ‘Printer’ selector.
The display above shows the parameters for the printers as default. These parameters 
may be different in other countries or may have been specially confi gured for some 
customers.
Clicking on the ‘Test  Page’ button will print a page showing the current printer 
confi guration and image quality verifi cation graphics.

Menu  Bar
File Menu:
• Import – Load a confi guration fi le that was saved previously using the 
Export feature. 
NOTE: You must then Save Confi g to set the printer to this confi guration.
• Export – Save a confi guration to a fi le. 
NOTE: Bluetooth information is no longer stored in this fi le. If an old fi le has been
    loaded, the Bluetooth information will be written to the default confi guration fi le.
• Select Printer – Displays the currently available print queues for your printer, 
along with the port name, to make it easier to select the proper printer in case 
you have more than one print queue available. This will also modify the Printer 
selected on the main dialog.
  Bluetooth Menu:
If your printer is enabled with  Bluetooth, you may use this menu to name our printer, 
create your own PIN password for your printer.  Some hosts require PIN codes, and for 
others, this feature is optional. 
						

							Page 19 Selecting “Bluetooth Settings” will display the following screen where you will have 
the choice of setting two parameters, the PIN code and the Local Name.
Setting a new PIN code limits access to your printer to only a host that has the correct 
PIN code.
Setting a new Local Name allows identifi cation of this particular printer where multiple 
printers are available and discoverable.
Both the PIN code and the Local Name must use alphanumeric characters (A-Z, a-z, 0-
9) only. The Local Name can contain a space character, but the PIN code cannot. If you 
enter a character that is not allowed, the following screen will be displayed:

Confi guration Options (Dropdown Menu Selections) 
NOTE: These confi guration options are in most cases relevant only where the host 
              computer will be sending simple text data to the printer and does not have a 
              Brother-supplied driver available.  The options which are common to all 
    operating systems include Auto-On, Auto-Off , and Pre-feed.
  Printer:
This selection lists print queues that exist for the printer.  In most cases only one 
queue will be displayed.  If the queue lists more than one printer, select the one that 
corresponds to your connected printer.
If using text mode, the following options should be set by the user.  In non-text mode, 
they will be set automatically by a Windows driver. 
Paper  Size:
                                 
						

							Page 21
For standard paper  sizes, this setting determines default margins and expected length 
for each printed page.  For ‘Custom’ sizes, margins and length may be set using the 
commands ‘Form Length’, ‘Bottom Margin’, ‘Left Margin’ and ‘Right Margin’.
‘Letter’ size assumes an 8-1/2 x 11” page, and sets a total printable height of 10.67”, 
which in turn provides for a top margin of about 0.27”, and a bottom margin of about 
0.06”.  Printable width is set to 8.16” with 0.17” margins on either side.
‘Legal’ size assumes an 8-1/2 x 14” page, and sets a total printable height of 13.67”, 
and top and bottom margins of about 0.27” and 0.06”, respectively.  Printable width 
is set to 8.16” with 0.17” margins on either side.
‘A4’ size assumes an 8.27 x 11.7” (210 x 297mm) page, sets a total printable height 
of 11.36” (288.5mm), top and bottom margins of about 0.27” (6.9mm) and 0.06” 
(1.5mm) respectively.  Printable width is set to 8.0” (203.2mm) with 0.13” (3.3mm) 
margins on either side.
‘Custom’ size allows the setting of length of the form, bottom margin, and left and right 
margins using those commands.
A Note about Text  Mode:
The Printers can print either Raster Graphics or Text Mode.  The choice is determined 
automatically by the data stream sent from the host device to the printer.
Raster Graphics is the most common form of usage for the PocketJet.  The printer 
uses bit-mapped graphics as opposed to text.  What you will see is WYSIWYG 
– what you see is what you get – meaning that what is on your computer screen is 
what is printed.
In Text Mode, the Printers will print only the characters contained in the resident 
character set.  For the PocketJet 3 and PocketJet 3 Plus, this character set is the 
Epson
® ESC/P emulation in native serif and sans serif fonts in 10, 12, 15cpi, and 
proportional sizes.
Print  Density:
                                
This sets the default print density (darkness) of the printing.  Darker print will use more 
battery power, but may be easier to read if the font or other printed information is 
made up of very narrow lines.  If battery conservation is more important, adjusting 
the setting for lightest print will do so.  ‘Low’ = lighter, and ‘High’ = darker print.

Form Feed  Mode:
                                
This setting affects what the printer will do in response to a Form Feed command 
from any source.  Different modes are appropriate depending upon the type of 
paper being used.
‘Fixed Page’ mode is typically appropriate.  It assumes a known page length (based 
upon the ‘Form Length’ and/or ‘Paper Size’ settings).  It advances a new sheet to the 
printing position, and attempts to eject it at an appropriate distance based upon the 
length of the page.
‘End of Page’ mode makes no assumptions about page length, and will continue to 
feed the paper forward to a maximum page length of 14” or until the Paper Sensor 
detects that no paper remains in the input of the printer.  Note that either the end of a 
cut sheet, or the black mark printed on the back of certain roll and perforated paper, 
will be detected as the end of a page.
                         
‘No Feed’ mode ignores all Form Feed commands, and does not advance the paper 
after printing.  This can be of particular help to roll  paper users who are printing only 
partial pages and do not wish to waste additional paper at the end of each document.  
The page may be manually advanced using the Main  Switch.
Auto- On:
                              
When external power is applied to the printer, there are three possible actions that the 
printer may take.  
If Auto-On is set to ‘Disabled’, the printer will place itself in a “sleep” state where 
minimal power is used.  The Main  Switch must be pressed to wake the printer up 
for printing.
If Auto-On is set to ‘Enabled’, the printer will power up as soon as an external  
						

							Page 23
power source is connected to the printer.  This can be useful in certain mobile 
installations where access to the Main  Switch is diffi cult or unavailable.
If Auto-On is set to ‘Enabled-No Main  Switch’, the printer will power up as soon as 
an external power source is connected, and furthermore, the Main Switch cannot 
be used to turn the printer off.  This may be useful in some mobile installations 
where the button could be accidentally pressed.   Power must be disconnected to 
shut off the printer.
Auto- Off:
                                
When the printer is running on battery power, you may wish to have the printer turn 
off automatically to conserve the battery.  You may choose to disable this feature by 
selecting ‘None’, or you may select either a 10-minute or 30-minute time-out period.  
If no data is received within the period selected, the printer will turn itself off.
Pre-Feed:
                                
When the printer is powered on and paper is found in the paper input slot area, 
the printer will normally advance the paper a short distance.  This is the default 
‘Enabled’ operation of the printer.  However, roll  paper users who leave paper 
loaded while powering the printer up/down may fi nd that this is inconvenient as it 
will misregister the top of form on pre-printed and perforated roll  paper.  Those users 
will likely wish to ‘Disable’ this feature.
CR-LF Mode:
                                 
						

							Page 24 This command determines what the ESC/P
® emulation does with ASCII characters 10 
and 13.  These are the ‘line feed’ (LF) and ‘carriage return’ (CR) characters.  The 
“LF” causes the printer to move down to the next print line, and the “CR” causes the 
printer to move back to the left margin position.  In most cases, these are sent at the 
ends of lines to position the printer for the next line of text.
Some host computers send one or the other of these, and some send both, each hoping 
to move to the left margin and down to the next line.  You can determine the effect 
of these characters when they are received.  If your host sends only a CR or LF to 
complete each line, you should set this to LF=CR+LF CR=CR+LF so that both a 
carriage return (return to left margin) and line feed are executed when just one of 
these control codes is received by the printer.

Form Length:
   
This command can be used to set the form length of a ‘Custom’ size page.  You may 
specify the vertical print area in text lines as defi ned by the ‘Text Line Spacing’ 
setting, or in inches.
If using the ‘Lines’ method for setting “custom” form length, the physical height of  
the page is determined by the vertical space per line as determined by the ‘Text Line 
Spacing’ command.  The minimum value allowed is the number of lines that would 
equal at least one inch of print because this is the minimum length of paper that will 
feed properly through the printer.  For example, if your current ‘Text Line Spacing’ 
is set to 6 lines per inch, you must specify at least ‘6’ lines of form length.  The 
maximum setting is 127 lines.  For 6 lines per inch, that will provide a page of a little 
more than 21 inches in length.
If using the ‘Inches’ method for setting form length, the physical height of  the page 
is rounded down if needed to create an even number of print lines as determined by 
the ‘Text Line Spacing’ command.  For example, if your ‘Text Line Spacing’ is set 
to 6 lines per inch, and you specify 9.6 inches, the application will determine that 57 
lines could be printed in this space, and change your inch value to (1/6 x 57) and the 
display a form length of 9.5 inches.
If you switch modes from ‘Lines’ to ‘Inches’, the form length will be recalculated in 
inches and displayed accordingly.  If you switch from ‘Inches’ to ‘Lines’, the form 
length will also be recalculated and displayed as the number text lines that will be 
printed as shown in the example below.

Bottom Margin:
   
This setting will modify the bottom margin when ‘Page Size’ is set to ‘Custom’.
‘Lines’ allow you to set a bottom margin equal to the height of a specifi c number of text 
lines.  The actual space that is left depends upon the current setting of the ‘Text Line 
Spacing’ setting.  For example, if ‘Text Line Spacing’ is set to 1/6”, and the ‘Bottom 
Margin’ is set to ‘4’ lines, 2/3” of blank space will be created at the bottom of 
each page.  
The minimum and ‘default’ space between pages will depend upon the setting 
of the ‘Text Line Spacing’, but is a minimum of  1/2”.  For 6 lines per inch, the 
minimum is 3 lines; for 8 lines per inch, 4 lines; for 8 lines per inch at 0.12” spacing, 
5 lines.  Note that if the “Form Feed  Mode” is set to “No Feed”, the bottom margin 
will be forced to “0” lines as a reminder that no margin can be set and none will 
be produced.
The maximum setting is the ‘Form Length’ in lines – 1.
