Print user-defined bit image
GS 0
1DH 30H
<29> <48>
<name> = a 15-byte maximum length name to identify the image.
GS 0 prints a bit-image from storage in the nonvolatile memory pool. The
name of the bit-image can be from one to 15 bytes long and contain any
alphanumeric characters as well as spaces. GS . searches the nonvolatile
memory pool for the first occurrence of the image identified by <name>. If
the image is found, it will be printed. If the image cannot be found, this
command will be ignored. In standard mode, this command must be
entered at the beginning of a print line. In page mode, this command may
be entered at any time.
The following basic example demonstrates how to print the stored bit-
image named "MY IMAGE":
PRINT #1, CHR$(29), CHR$(48),
PRINT #1, "MY IMAGE", CHR$(0)
Erase a single entry from the nonvolatile memory pool
GS 1
1DH 31H
<29> <49>
<name> = a 15-byte maximum alphanumeric name to identify the image.
GS 1 deletes a single entry (bit-image or character set) from storage in the
nonvolatile memory pool. The printer will go off-line before deleting the
entry and will return on-line when it is completed. Please be sure to adhere
to flow-control provided by the communication interface.
Erase all entries from the nonvolatile memory pool
GS 5
1DH 35H
<29> <53>
GS 5 erases the entire contents of the nonvolatile memory pool and frees
up the memory for new entries. The printer will go off-line when this
command is received and will return on-line when it is completed. Please
be sure to adhere to flow-control provided by the communication interface.
