|
Format: | 1B |
|
Printers: | 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. |
|
275EMUL: | No operation. |

Command: | Interchange Record Separator (IRS) |
|
Format: | 1E |
|
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. |
