4.2.12. Resetting the horizontal margins
Esc9 (27)(39) <1Bh><39h>
This command resets the left and right margins to the left and right edges of the logical page respectively.
4.2.13. Setting the top margin
Esc&l#E (27)(38)(108)#(69) <1Bh><26h><6Ch>#<45h>
# stands for the distance between the top of the logical page and the top margin in rows.
 The row height is as defined by the VMI. If you subsequently change the VMI (or the line spacing) the top
margin position that you have set does not change - that is, when you specify the top margin position it
remains fixed physically until you specify a new one or reset it to a default value.
 The top margin command is ignored if you try to set a margin greater than the current length of the logical
page.
 The top margin command is ignored if the current VMI is 0.
 The factory default top margin setting is half an inch below the top of the logical page.
 Depending on your model, the top margin can be set from the printer's control panel (see the User Guide).
