Verifying the Printer and
Host Connections
In this chapter, you verify that the host computer can send files to the printer.
This chapter assumes that the printer and the printer drivers have been properly
installed as explained in the previous chapter, “Installing the Printer and
Drivers.”
Verifying printing from a PC
Direct DOS connection verification
Verify that the PC can communicate with the printer.
1.
Power up the printer and the PC. If the PC is running under
Windows, exit Windows so that the PC is operating under DOS alone.
2. At the DOS prompt, type (in lowercase) the following:
echo showpage > port:
Substitute port: with LPT1 :, LPT2 :, or COM1 : etc. or whichever
corresponds to the port the printer is attached to.
The printer should respond by picking, processing, and ejecting a blank sheet of
paper; if this does not happen, check your cabling. Ensure that you have the
port properly configured as explained in the topic, “Cabling the printer” on
page 2-10.
Windows 95 driver verification
Using the Windows Write application, verify that the PC, running under
Windows 95, can print to the printer.
1.
If it is not already running, start Windows 95
2. Launch a simple text program such as one of the Windows 95
programs Notepad or WordPad. (If Notepad or WordPad is not
available, you can use any other text editor-type program.)
3.
Type in a line of text such as
