For neighbour I installed ok the above printer. All running smoothly,test page ok, until suddenly got EPSON message "printer is off-line". However, the printer was on-line using LPT1 Printer Port & printer cable. Went through Windows troubleshooter & no joy. Did change cable but no joy. Printer has the green on-line light showing."printer is off-line" message still showing. Even un-installed & re-installed but again nothing. Any ideas anyone?
When you start the system, keep pressing the del key (that's the most common way of enterng the BIOS - it usually shows it on the initila boot up screen).
On the BIOS front page, you wll see a menu - use the cursor and enter keys to select the page "Integrated Peripherals".
On there will be a setting for the Parallel Port. Use the page up and page down keys to change it's setting. If it's set to SPP try ECP and/or EPP and/or ECP/EPP. The normally recommende setting for Epson and HP printers is ECP - but try chaging it anyway.
If your BIOS is not exactly like this - you may have to hunt around a bit for the settings.
