Black Box PC124C Installation Manual page 102

To aid in readability, a single space is allowed between hex bytes, but is
not included in the string.
The strings could specify a special font-selection command or other
custom command to be sent directly to the printer.
This command, if placed as the first printable data at the top of the page
(position 1, line 1), will be sent to the printer prior to the data.
To change a custom user string, simply input the new custom user
string values; the old string is automatically erased.
Example: &%Z55,3(1B01) defines the &%U3 custom user string to send an
"Escape and SOH" (1B and 01 hex) to the printer which is the double wide
command).
COMMAND 57: HOST-PORT INITIALIZATION STRING
Allows the user to define an initialization string of up to 25 bytes, which is stored in
the memory of the interface and is sent to initialize the printer for host printing
after shared port printing has occurred. The interface also restores the host page
format parameters after sending this string and prior to host printing. The
initialization string is sent at the beginning of each page.
VALUE
1(max. 25 bytes of ASCII hex code)
1()
To aid in readability, a single space is allowed between hex bytes but is
not included in the string.
The coax-port initialization string is only sent to the printer when you
turn the printer on and after printing by the shared parallel port has
occurred.
Host SCS commands and download commands have priority over the
initialization string instructions.
To change the initialization string, simply input the new command
values. The old string is automatically erased. To delete the
initialization string from the permanent memory, simply type the
parentheses with nothing between them.
