3812, 5219

 

Action:

Causes the current print position to be moved one

 

character to the left.

 

 

On the 3812, Back Space can cause the current print

 

position to move to the left of the logical left margin.

 

On the 5219, Back Space will not move to the left of the

 

logical left margin unless a Release Left Margin (RLM)

 

command has been received on the current print line.

IBMEMUL:

Same as the 5219.

Printers:

3812, 4214, 5219, 5224, 5225, 5256

 

Action:

Performs a Carriage Return (CR) and a Line Feed (LF).

 

If the current print position is on the last line of the

 

logical page, it performs an automatic Form Feed (FF),

 

and printing continues on the first line of the next page.

 

Most IBM host system print spoolers use the Form Feed

 

character to delimit and count pages. For this reason,

 

only Form Feed should be used to move to a new page.

 

Interchange Record Separator should not be used to

 

move to a new page.

 

IBMEMUL:
