data from external media
Format
RWER R, medium, data-type[, ’partition-name’];
Parameters
medium:
0 = hard disk or RAM disk
A = memory card
E = EPROM
data-type:
2 = Printable data
128 = API data (downloadable program)
partition-name:
Name of partition from which data is read, a maximum of 15 printable ASCII characters
Function
The RWER R command reads data from any external media whether it is a memory card,
hard disk, EPROM, or RAM disk.
Only data types 2 and 128 are allowed. Note that reading data of other data types, such as
fonts and macros, does not require this command since the printing system automatically
reads them at power up.
If the same partition name exists on different external media, the priority with which data
is read is as follows.
The partition name may be a maximum of 15 printable ASCII characters (20H through
7EH); upper and lowercase letters are regarded as distinct. A partition name may not
have leading spaces, and in the command, the partition name must be enclosed in single
or double quotation marks.
This command causes a page break.
