User-Defined Characters, Transmit
Purpose:
Uploads a graphic from the printer in the form of commands and data the
printer receives to create the graphic.
Syntax:
<ESC>u n
The graphic ID number is n. It has a range from 0 to 99.
Notes:
Sending <ESC>u to the printer without designating a parameter causes it to
upload the entire graphics directory. The syntax of the directory is:
IDnumber, name, type, storage size<CR><LF>
type = 100 for UDC or graphics
If the printer is in Advanced mode, each data byte represents six bits of the
graphic bitmap. If the printer is in 86XX 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.
User-Defined Tables, Transmit
Purpose:
Causes the printer to upload the user-defined command and protocol tables
that the printer receives to download a new command set.
Syntax:
<ESC>Z t
The command table identifier has the following values:
t = 0
t = 1
t = 2
t = 3
t = 4
You can find tables listing the default values under "User-Defined Interface
Notes:
Tables" later in this chapter.
The printer generates an error code (12) if you enter an invalid number. Use
this command to substitute protocol and command characters.
