Application Software

Because the family of Epson printers shares a great many commands, you can use an application progam even if it does not list the LQ-850 or LQ-1050 on its printer selection menu. If the printer is not listed, choose one of the following printers They are listed in order of preference.

LQ-850 (LQ-1050)

LQ-800 (LQ-1000)

LQ-510/LQ-500

LQ-1500

If none of these printers is listed, select the first one available on the following list: LQ, EX, FX, LX, RX, MX, Epson printer, Standard, printer, Draft printer.

To use all of the features of the printer, however, it is best to use a program with the LQ-850 or

LQ-1050 on its menu If your program does not list the printer, contact the software manufacturer to see if an update is available that supports your model.

Installation/Support Tips

Short Tear Off

To activate the short tear-off feature on the printer, first turn DIP switch 2-7 to the on position. To control it through the software, send a form feed command at the end of each page. After sending a form feed, do not sand it any more data for a 3second interval.

Single-Sheet Loading

When loading single sheets, make sure that the paper lever is set to single sheets, not tractor paper. The paper can be loaded manually or via the auto load button. Before attempting to load in the paper, wait for the platen to lock in place after changing the paper lever.

Setting up the Page Length

The page length has to be adjusted for using single sheets and for using tractor paper. When your software you asks you to set up the number of lines/page, single sheets require a shorter page length than does tractor paper. Set the page length to 61 lines for single sheets (also when using the cut-sheet feeder) and 66 lines for tractor paper.

Software

The type of printer installed on your system must be identified for each software package. This is usually done through a setup menu. If the LQ850/1050+ is not listed in the software pa&age, any Epson 24-pin driver will be compatible.

DIP Switch Settings

The default settings will usually work for most applications, but they should be checked before using the printer. This will avoid unexpected results.
