With Windows 95, why does the first page print garbage on the first line ("@JPL" or "E"), but the rest of the document prints fine?
This is caused by either a setting in your computer's CMOS for the parallel port or by a conflict in the lpt.vxd file in Windows 95. This is not a driver problem or a printer problem. Windows is sending a signal to the port that the printer is misinterpreting. Try these things to get resolution.
Click Start at the lower left-hand of the screen.
Choose settings, then printers.
Select the printer icon, choose the File menu, then select Properties.
Click the Details tab near the top of the screen, then select the Port Settings from the lower right.
Remove the X from the Check Port Before Printing box.
If this does not correct the problem, try to configure the printer in your computer's CMOS settings to non-PS/2 mode (if your computer supports it). For example, use standard LPT, EPP or ECP mode. Do not choose EPP/ECP. If the problem still persists there is an updated file called "lpt.vxd" on the Windows 95 CD-ROM that corrects this problem.
Microsoft has released the following information about this problem:
Configure the port in your computer's CMOS to a non-PS/2 mode (use standard LPT, or ECP mode). Note: this option is not supported on all computers.
Update your lpt.vxd file with the file on the Windows 95 CD-ROM.
