Epson LX-800 - Prints NLQ Differently Than In
DocumentID: 608857

The information in this document applies to:
WordPerfect® 5.1 for DOS

Problem

Solutions: A customer wanted the Epson LX-800 printer to print the Near Letter Quality (NLQ) with only one pass on the characters. The WordPerfect 4.2 Program printed NLQ in this manner. The PRHELP Program for WP 4.2 lists the first font (10,1) as an EMPHASIZED print instead of an NLQ font.

As a work around, the customer put the codes into WP 5.1 for the emphasized print and set the font to Draft in WP. The Epson LX-800 printed with the desired quality with only one pass over the text.

NLQ is different than emphasized print. This information is also the case with most Epson printers. NLQ codes are <27>x<1>, and the printer will make two passes over the line. Emphasized print codes are <27>E, and the printer will only pass over the line once. The print quality is a bit better with NLQ, but it is relatively similar. These codes were taken from the Printer Program in WP 4.2 as follows:

1.      Type PRINTER at the DOS prompt (The Printer Program is found on Printer 2 Disk for WP 4.2).
2.      Select 3 for Printer Definitions.
3.      Select the number of the desired printer (in this case the Epson LX 80/800), and press Enter.
4.      Select 8 for Selecting Fonts 1-4. The codes shown for "Shift into Font 1" are <27>E. Since the D is a Carriage Return in the WP 4.2 Printer Program, the is not necessary.
5.      Look at "Shift Into Font 2;" the codes are <27>x<1>. The is not necessary for this option. (WP 5.1 doesn't understand it, and the code will print when the user inserts it as a printer command in WP 5.1.).

The user didn't make changes in the Printer Program because he only wanted the change occasionally. The user created a macro that inserted a printer command with the codes for emphasized print (<27>E) and exited back to the document screen. The macro then set the text quality to Draft (or the printer would still make two passes on the line and be very slow).

To put the printer command in the document do the following:

1.      Press Shift-F8, 4, P, P, 1, and type <27>E
2.      Press Enter and F7
3.      Press Shift-F7, T, 2

NOTE: Bold will no longer work with this change to the printer definition. This will do a different kind of NLQ. It is not recommended by WPCorp, because WordPerfect uses the Emphasized codes for Bold in some instances, and Bold would not print. This printer was designed to do NLQ with the [27]"x"[1] command, and that is how it is supported by WPCorp.
