Storage Area Usage, Transmit
See the Memory Usage, Transmit command.
Test and Service Mode, Enter
Purpose: Enters Test and Service mode.
Syntax: <ESC>T
Notes: The printer completes all print jobs before executing this command. When
the printer enters Test and Service mode, it erases any host-entered data
that was sent prior to the command.
User-Defined Characters, Transmit
Purpose: Uploads a graphic (user-defined character) from the printer in the form of
commands and data the printer receives to create the graphic.
Syntax: <ESC>un
where n is the graphic ID number.
Printers:
Printer Default Values for n Notes
All None 0 to 99
All printers support this command the same
way.
Notes: If you send <ESC>u to the printer without specifying a value for the n
parameter, the printer (except for the 3400A, 3400B, 3600, and 4400)
uploads the entire graphics directory. The directory appears in this format:
[IDnumber] [name] [type] [storage size]<CR><LF>
where:
IDnumber
is the graphic number that was specified by n in the
command that created the graphic.
name is the optional graphic name that may have been specified
by ,name in the command that created the graphic.
type is 100 for a graphic.
storage size is the number of bytes to store the graphic.
If the printer is in Advanced mode, each data byte represents six bits of the
graphic bitmap. If the printer is in Emulation mode, each data byte
represents one bit of the graphic image.
The printer generates an error code (28) if you enter an invalid number.
