images.
Memory sector is full - The sector can store up to 64 KB of graphics data,
after which the sector is full.
Predefine Messages
RS-232 Syntax:
GS : message_num data GS : or X'1D3A;message_num;data;1D3A'
where:
message_num
The message number being stored.
1 ≤ message_num ≤ 25
data All data and commands to be included in this message. No
immediate commands can be included in the data.
Purpose:
To store predefined messages. This cuts transmission time. This is where
you can store the header and the trailer of receipts, for example.
Remarks:
v After a ″GS :″ occurs, all incoming commands are stored in the message
until another ″GS :″ occurs.
v “Print Predefined Graphics (Logo) Command” on page 151 can be
included in this command.
v The size of all predefined messages cannot exceed 8000 bytes.
Example:
Store a trailer message:
X'1D3A01'
’Thank You For Shopping’ X'0D'
’ At RSD STORE’ X'0D'
’Store #1234567’ X'0D'
X'1D3A'
This would store this message as predefined message 1. See “Print
Predefined Messages” on page 152 for printing this trailer message.
Commands for selecting the print station and print characteristics must be
included with the stored message.
Limitations:
v “Print Predefined Graphics (Logo) Command” on page 151 can be
included in this command. Select and print a graphics command cannot
be used. See “Print Graphic Messages” on page 150.
v “Print Predefined Messages” on page 152 can be included in this
command, but can only be nested one message deep.
Example: Store a predefined message (’Jane Doe’) at location 3, then
issue the following commands:
