user-defined characters, downloaded bitmaps should be defined only
after completing this command. The printer clears the receiving and
printing buffers and resets the printer to the mode that workable when
power on. (hardware reset interface is not supported )
This command cancels all NV bitmaps that have already been
defined by this command.
From the beginning of the processing of this command till the
accomplishment of hardware reset, mechanical operations (including
initializing the position of the print head when the cover is open, paper
feeding using the FEED button, etc.) cannot be performed.
During this command processing, the printer is busy and stops
receiving data when writing data to the user's NV memory. Therefore,
data transmission, including real-time commands, is prohibited during
the execution of this command.
NV bitmap is a bitmap defined in non-volatile memory, Define FS
p printing with FS q.
In standard mode, this command is valid only when processed at
the beginning of the line.
This command is valid when 7 bytes <FS yH> of the command
are processed normally.
When the data volume exceeds the left capacity of the range
defined by xL, xH, yL, and yH, the printer will process the range
defined by xL, xH, yL, and yH outside the defined range.
In the first group of NV bitmaps, when any one of xL, xH, yL, yH is
out of the definition range, this command is disabled.
In groups of NV bitmaps other than the first group, when xL, xH,
yL, yH out of the defined range, it stops processing this command and
starts writing into the NV images. At this time, NV bitmaps that haven’t
been defined are disabled (undefined), but any NV bitmaps before that
are enabled.
The d indicates the definition data. In data (d) a 1 bit specifies a
dot to be printed and a 0 bit specifies a dot not to be printed.
This command defines n as the number of a NV bitmap. Numbers
rise in order from NV bitmap 01H. Therefore, the first data group [xL
xH yL yH d1...dk] is NV bitmap 01H, and the last data group [xL xH yL
yH d1...dk] is NV bitmap n. The total agrees with the number of NV
bitmaps specified by the command FS p.
The definition data for an NV bitmap consists of [xL xH yL yH
d1...dk]. Therefore, when only one NV bitmap is defined n=1, the
printer processes a data group [xL xH yL yH d1...dk] once. The printer
uses
([data:
(xL
xH× 256)×(yL
yH× 256)×8]
[header :4]) bytes of NV memory.
The definition area in this printer is a maximum of 192K bytes. This
