Dot-Matrix Printer Check
Use this option to check the following:
l
The operation of your printer in IBM-compatibility mode
l
The compatibility of your printer with the extended character
set used by the Equity LT-286
l
The ability of your printer to produce bit-image graphics and
print images from the graphics screen.
When you select option 14 from the DEVICE LIST, you see this
prompt:
Is dot-matrix printer on-line (Y/N)?
Check that your printer is connected to the computer, and that it is
turned on, loaded with paper, and on-line. Press Y and then
Enter
to continue, or press
N
and
Enter
to return to the menu.
When you continue the test, the computer checks to see whether
the printer is responding correctly. This test detects whether the
printer is off-line or whether an interface error exists. If no errors
occur, the computer sends a repeating sequence of ASCII
characters and dot graphics data to the printer until you press any
key. The pattern looks like this:
The text data includes all the characters commonly used by
programs that require foreign languages or graphics characters. If
your printer prints different characters from the ones you see in the
illustration, you may need to take care with certain software.
The bit-image graphics data is sent to the printer using a command
(ESC K) compatible with Epson and IBM printers. If this pattern is
printed correctly, you can use the MS-DOS GRAPHICS or
GRAPH24 program to print out copies of graphics screens.
