Execute vertical tab  
Code:  
 
0Bh  
Outline:  
Feeds the paper to the next vertical tab set position. When a vertical tab is not set, line feed is not performed. If 
the current line is at or below the last vertical tab set position, the paper feeds to the top of the next page.  

Function:  
Set vertical tab position  
Code:  
"B" n1 n2...nk  
1Bh 42h n1 n2...nk 00h  
Definition Range:  
1 <= n1 <n2 <n3...<nk <= 255, 1 <= k <= 16  
Outline:  
Cancels all current vertical tab positions and sets new vertical tab positions at lines n1, n2, where n1, n2 are 
numbers between 1 and 255. A maximum of 16 vertical tab positions can be set. The tab positions must be 
specified in ascending order; any violation of ascending order terminates the tab position list. Standard 
termination is by the control code. The vertical tab positions are set in terms of the current line spacing and do not 
move if the line spacing is changed later.  
Note:  
If a tab set position <nk> is equivalent or smaller than <nk - 1> just preceding the tab set position, setting of 
vertical tab is assumed as complete.  

Function:  
Set bottom margin
