Epson 4100 manual Bi-Directional Graphics / NLQ

68 Configuration

On: The printer prints near letter quality (NLQ) characters in 10 12, and 15 pitch (10, 12, and 15 char/in.). NLQ characters have about two to three times the dot density of draft quality characters. NLQ characters are more attractive than comparable draft quality characters.

Most NLQ characters can be bolded and/or italicized.

Bi-Directional Graphics / NLQ

Pressing YES prints out the active NLQ status:

•Off (factory default)

•On

Normally, all draft text is printed bi-directionally, that is, on right-to-left as well as left-to-right passes of the printhead carriage. This option lets you enable or disable bi-directional printing of all non-draft text and graphics. Non-draft text and graphics include graphical images, barcodes (except PostNet printed as text), and NLQ text.

Consider enabling bi-directional printing if you normally print NLQ text and/or routinely include graphics. Bi-directional printing approximately doubles throughput, thereby increasing efficiency. Enabling bi-directional printing overrides all uni-directional printing control commands sent by the host.

Consider disabling bi-directional printing if barcode readability is a problem. (Also, setting the “Barcode Density” in the configuration menu from 75 dpi to 100 dpi may enhance readability.)
