Defining Print Density and Other Options 3
1 Print Density
Available settings: [0]-[10]
Default setting: [6] (PJ-623/663), [4] (PJ-
622/662)
This parameter determines print density, which
affects the darkness of the printed document. A
lower value produces lighter print; a higher
value produces darker print.
Darker print uses more battery power, but may
be easier to read if the font or other document
content is made up of narrow lines. If battery
conservation is important, select a lower value.
Note
If this parameter is changed in the printer
driver’s dialog box, that setting has priority.
2 Form Feed Mode
Available settings: [No Feed], [Fixed Page],
[End of Page], [End of Page Retract]
Default setting: [Fixed Page]
This parameter determines how paper is
ejected; it determines how the printer responds
to form feed commands received from any
source.
No Feed - Paper is not fed at the end of a
job. Because additional paper is not
ejected when at the end of the document,
this setting is useful when using
non-perforated roll paper.
Fixed Page - Paper is fed at the end of a
job to suit the vertical length of the selected
page size (i.e., letter, legal, A4, or
user-defined size). Select this setting when
using cut sheet paper.
End of Page - Paper is fed until the printer
detects that no paper remains in the input
slot, or until 14" (355.6 mm) of paper has
been fed. Select this setting when using
perforated paper.
End of Page Retract - Paper is fed until the
paper sensor detects a pre-printed
end-of-page mark on the paper or the end
of the sheet. When this setting is selected,
set [Paper Type] to [Perforated Roll
Retract].
Note
If this parameter is changed in the printer
driver’s dialog box, that setting has priority.
3Pre-Feed
Available settings: [Disable], [Enable]
Default setting: [Disable]
If [Enable] is selected, the printer ejects a short
length of paper when the printer turns on.
When using perforated roll paper or roll paper
that is pre-printed, we recommend setting this
parameter to [Disable].
4 CR-LF Mode
Available settings: [LF=LF CR=CR],
[LF=CR+LF CR=CR+LF]
Default setting: [LF=LF CR=CR]
This parameter determines how the printer
responds when LF and CR commands (ASCII
characters 10 and 13) are received. By default,
the print head advances to the next line for an
LF (line feed) command, and the print head
returns to the left margin for a CR (carriage
return).
