#dot rows = n x 24, n = 5 is the recommended setting

Because the printhead and cutting knife are physically separated, it is necessary to advance the printed area of a 
receipt past the knife to avoid the last of the printing from being cut off. This advance of paper however, causes a blank 
space at the start of the next receipt that could be used.  To utilize this space and  reduce paper usage, this command 
starts to print a logo for the next receipt before initiating the cut at the end of  the current receipt. At a set location 
during the printing of the logo, the corresponding paper advance is stopped and a paper cut performed.

The formula “n x 24” is used to determine the number of dot rows to move the paper from the start of the logo to the 
position of the cut.  

If n x 24 is greater than the height of the logo, the logo height is used to determine the cut position.  If n = 0 the cut is 
eliminated.  

In order for this command to function properly, all commands used by legacy applications to move the end of the 
current receipt past the knife should be removed.

See “Print downloaded bit image” command.

Default:  

0 - normal speed 

This command sets a specific speed for an operation, allowing the user more control of the print environment. 

The speed is maintained as long as it is less than the speed automatically set by power management. A parameter of 
zero (0) restores the normal max speed.
