Printronix P3000 Series manual Vertical Tab Positions, Executing Vertical Tabs

Vertical Tab Positions

Vertical tab positions are assigned to a line number. A maximum of 16 vertical tab positions can be assigned on the form. A sample format is shown in Figure 5–1. The first vertical tab is assigned line 6 for part number data, a second tab is assigned line 8 for part name data, and a third tab is assigned line 14 for quantity data.

The ESC B code is used to assign the vertical tabs to the lines of the form. Once the tab positions are assigned, sending the vertical tab execute code (VT) causes the paper (currently at the top–of–form position) to advance to the first tab position for PART NUMBER data. Sending another VT moves the paper to the second tab position for PART NAME, followed by a third VT to access the third tab posi- tion for QUANTITY data.

Executing Vertical Tabs

The vertical tab execute code is VT. When sent, it prints the contents of the print buffer (if data is in the buffer) and causes paper movement to the next predefined vertical tab position. If a tab position is not defined, the paper is moved to the next line at the current line spacing. If a tab position is at the current line, the paper is moved to the next tab position. If no tab positions are defined between the current line and the end of the form, the paper moves to the next top–of–form.
