Horizontal Tab

This command moves the print position to the next tab position set by the Set Horizontal Tab Positions (1B 44 n1 n2 ... 00) command. The print position is reset to column one after each line. The tab treats the left margin as column one; therefore, changes to the left margin will move the tab positions.

When there are no tabs defined to the right of the current position, or if the next tab is past the right margin, line feed is executed. HT has no effect in page mode. Printer initialization sets 32 tabs at column 9, 17, 25, … (Every 8 characters)

Example:   

MSComm1.Output = Chr$(&H09)
