The LCC command is valid only while the printer is in the home state, and
remains in effect until the printer receives the next LCC. The format of the data
field (DATA) for this command is:

Note: Subsequent LCC commands nullify previous Overlay IDs or Suppression
IDs from previous LCC commands.
Copy Modification is an optional modification keyword list made up of two byte
controls:

Valid values for copy modification are:

Simplex Printing is printing on only one side of the document. This is the only
type of printing the IBM 64XX Line Matrix Printers can perform.
Suppression ID allows the later suppression of text data. The first byte of the
keyword, D1, specifies this keyword as suppression. The second byte of the
keyword specifies a suppression identifier. Valid suppression ID values are 01 to
FF. Print suppression occurs as follows:
1. The LCC command specifies one or more suppression ID values. (Each ID
2. The printer receives a Begin Suppression control (inside a Write Text
3. All subsequent text data does not print (text suppression), until the printer
4. All text data received after the End Suppression control prints normally.
Overlay ID allows later processing of specified overlays. The first byte of the
keyword, E1, specifies this keyword as overlay. The second byte of the keyword
specifies an overlay identifier. Valid overlay ID values are 01 to FE. An overlay

1. The LCC command specifies one or more overlay ID values. (Each ID must
