Parallel or serial connected (some models may not have the serial port).
"Q: Why does my printer print garbage from MS-DOS and Windows?
A: When a printer prints garbage, it usually indicates a faulty cable or a loose connection. Power OFF your printer and computer. Disconnect and reconnect the cable on the printer and computer. Once the cable has been reconnected, power the printer and computer back ON. Try printing from MS-DOS. If you are still getting garbage, change the cable. We recommend getting a fully shielded cable, preferably 6 feet or less in length. If you are still experiencing problems after changing your cable, you may have a computer or printer port issue. If you take the cable and printer to another computer and it works fine, have your computer's port checked by an authorized dealer. If it still gives you garbage from another computer, have the printer taken in to be serviced."
If you can try it with a different computer, try that.
If that computer has a built in printer port, check the parallel port mode in the bios (see the info below).If it has a PCI parallel port card, see the info below.
If the printer doesn't work properly with the other computer with the same parallel cable that worked fine previously, the parallel circuits in the printer are damaged.
If your model has the serial port too, try connecting the printer via that rather than the parallel connection. See the User manual.
If it's connected to a parallel port built into the mboard, the printer mode in the bios probably MUST be set to EPP, ECP, or EPP / ECP mode. Usually EPP mode works fine. ECP mode requires that there is a dma channel available - it may not be - you may be able to select one of more than one dma channel when you select ECP. The printer probably won't work properly if that's set to Standard or Bi-directional mode.
If it's connected to a PCI parallel port card,
- the card already supports one of those modes or both modes.
- don't install the card in the last PCI slot closest to the center of the mboard. That slot usually shares it's IRQ with the video and if so only PCI video cards are likely to not have problems when installed in that slot.
- the card may have a poor connection in it's slot
- make sure the card is all the way down in it's slot
- try removing the AC power to the case, removing the card, cleaning it's contacts with a tissue or soft cloth, installing it again.
You probably must use a parallel cable rated to support the IEEE1284 standards.
Use a cable that has IEEE1284 printed on the cable itself or on the end connectors. However, a cable that has individual wires that meet or exceed the minimum wire gauge for the IEEE1284 standard will work fine. The wire gauge is often printed on the cable, e.g. AWG xx - the lower the gauge number, the greater the diameter of the individual wires, the more likely it will work fine.
Parallel connections are NOT "hot pluggable". NEVER plug in or unplug the parallel cable when the computer is running.
Doing so can damage the circuits for the parallel port or the printer or both.
"after reformatting and installing Xp"
You MUST install the main chipset drivers for your mboard after XP's (or 2000's) Setup has finished. The main chipset drivers have *.inf files that tell the operating system the capabilities of the main chipset and if Windows does not have that info you're likely to have problems. If your mboard has USB 2.0 controllers the support for them and USB 2.0 devices is only built into Windows when it has SP1 or later Windows updates, and that built in support is NOT installed until AFTER the main chipset drivers have been installed.
(2000 must have SP4 or later Windows updates installed to have the built in support for USB 2.0 controllers and devices.)
" I installed the Epson dirvers for it (even though winxp includes drivers) ...."
" I have tried reinstalling the printer, different cables and different drivers "
You must un-install the Epson drivers in Add or Remove programs BEFORE you install them or other drivers again.
If you use the built into XP Epson LX 300 or 300+ drivers, you must manually select them. (If LX 300+ is not listed, the LX 300 ones will probably work fine, according to someone else who posted here who has a LX 300+.)
Whichever drivers you use, if you re-install the drivers, delete the printer model listing in Control Panel - Printers and Faxes BEFORE you re-install the drivers. (Un-installing the Epson supplied drivers may or may not do that automatically.)
