The printers listed above only accept Tandy control codes, and were
originally not designed to be PC Compatible.  Windows 95/98 was designed
specifically as a graphics user interface, and does not have drivers for
non-graphics type printers, such as daisy wheels.  In addition, as none of
these printer emulate (accept the same control codes as) any printers that
are specifically supported by MicroSoft Windows, you must choose the driver
"GENERIC TEXT/ONLY" when using them with Windows and Windows based
software.  This printer driver will allow  you print text, but not be able
to print any special fonts, bold-face, underline, super or subscripts or
and other special characters.  In addition, you will have very limited page
setup capabilities, and will be limited to a standard 8.5" x 11" page
format.

As these printers were designed to be used only on computers using either
the TRS-DOS, and XENIX operating systems, they all are designed to insert a
line-feed between each printed line, as these operating systems do not line
feed automatically.

The MicroSoft operating system does automatically line feed for each
printed line.  Therefore, when attempting to use these printers with
MicroSoft Windows 95 and 98, the printed information will be double-spaced.

Some of these printers, such as the Tandy DMP-400, have a switch that can
be used to eliminate this extra line feed.  Others, such as the DWP-210 do
not.  Therefore, on the printers that do not have this switch, you must
send a control code to the printer to eliminate the extra line feed.

Follow the directions listed below to accomplish this task:

1.   From the Windows 95/98 DeskTop, click on START, then SETTINGS, then
     double click on PRINTERS.

2.   The PRINTERS folder should appear.  If the GENERIC / TEXT ONLY
     printer driver has not yet been installed, double click on the icon
     labeled "ADD PRINTER".  If it has, proceed to step 10.

3.   The ADD PRINTER WIZARD dialog box should appear.  Click on NEXT.

4.  A list of printer manufacturers and model numbers should appear.
     In the list of MANUFACTURERS, select GENERIC.  In the list of
     PRINTERS, select GENERIC / TEXT ONLY.  Click NEXT.

5.   A dialog box listing printer ports should appear.  Select LPT1:,
     then click on NEXT.

6.   A dialog box asking for a printer name should appear.  If you wish
     to list the printer by name, you may type it in now.  If not, you
     can  leave the name GENERIC / TEXT ONLY as the printer driver
     name.  You will also see a check box asking if you wish this
     printer to be your default printer.  Select YES, then click on
     NEXT.

7.   You will be asked if you wish to print a test page.  Select YES,
     then click on FINISH.

8.   Windows will begin copying the files needed for the GENERIC / TEXT
     ONLY printer driver.  If your Windows 95/98 CAB files are one your
     hard drive, it should find them automatically.  If they are not,
     you may need to insert your Windows 95/98 CD.

9.   Once the files are copied, the test page should print.  You should
     note that there is a line feed between each line.  That is because
     the control code to prevent the extra line feed has not yet been
     added.  A dialog box should appear, asking if the test page printed
     correctly.  Click on YES.  You should be returned to the PRINTERS
     folder.

10.  Right click on the icon for the GENERIC / TEXT ONLY printer driver.
     In the menu that appears, click on PROPERTIES.

11.  The GENERIC / TEXT ONLY PROPERTIES dialog box should appear.  Click
     on the    DEVICE OPTIONS tab.

12.  Click the mouse in the data field labeled BEGIN PRINT JOB, so that
     the cursor is in that field.

13.  Press the <ESC> key on your keyboard.  "<ESC>" should appear in the
     data field.

14.  Hold down the <CTRL> key, and press the letter <U> on your
     keyboard. "^U" should appear, directly after the "<ESC>".   The
     field should now look like this:

     BEGIN PRINT JOB: <ESC>^U

     Click on APPLY.

15.  Now, click on the GENERAL tab, and click on the button labeled
     "PRINT TEST PAGE".  A new test page should print.  The line spacing
     on the test page should now be correct.

* NOTE: For this to work on the DWP-2 (260-1158), the printer must have a
        serial number later than 13010163.  At one time there was a BIOS
        ROM upgrade available for this printer that would allow this
        procedure to work, however, the upgrade is no longer available.

using these older printers with ANY version of MicroSoft Windows.
