What are the Epson Spool Manager and Epson Despooler?

The Epson Spool Manager manages special spool files called "journal" files. These contain the print data in an unprocessed form. The Spool Manager sends this data to the Epson Despooler for processing. The Despooler processes the data in segments, called "bands". Once a band is finished, it is sent to the printer for printing. While the printer prints, the Despooler works on the next band.

My printer will not power up when the cable is connected to by PC?

Power the Computer off and disconnect printer cable from the back of the printer. Power the printer off and back on again to verify that the printer will power on without the printer cable connected. Reconnect the printer cable and turn on the computer first and then turn on the printer. If the printer does not power up, try exchanging the printer cable by purchasing a fully shielded parallel printer cable. You can also try moving the printer and the cable to another computer. If the printer successfully powers on, you may have a problem with the parallel port on your computer. However, if this condition persists, there could be a problem with the parallel port on your printer. Take the printer to an Epson Authorized Service Center.

Why can't I print from one particular windows application, but I can print fine from other Windows applications?

Make sure that the correct printer driver and port are selected within the application that is not printing. Try printing again. If the problem persists, select the LQ570 printer as an alternative printer driver and try printing again. If the results are still unsuccessful, open the Windows Write program and try printing again. If you successfully printed from Windows Write,contact the software manufacturer.

My printer will not print from any DOS applications but will print from windows.

Try printing from the DOS prompt "C:\>", by entering "DIR >LPT1". If nothing prints, try printing to the LPT2 or LPT3 port. If successful, check the printer driver selection within the software program. Make sure the LQ or Stylus 300 driver is selected. Make sure the printer is set on the correct LPT port setting (the port should be set to the successful LPT port used from the DOS prompt LPT1, LPT2, LPT3).

After replacing the ink cartridge and the printer run through the motions of printing, however there is no ink printed on the paper.

Print out the demonstration page (press the ALT button while applying Power). If the problem persists and there is no improvement, take the printer to an Epson Authorized Service Center.

My output appears faded. How can I improve the quality
