Epson lx300+ii with serial port to fujitsu pc

I just bought a new epson lx300+ii and i plugged it with a serial cable to my fujitsu PC. When I print using a DOS based program, at first it printed a few delayed line and then it became hang. I plug back my old elpson lx300+ and it worked smoothly. I have set all setting and compare the setting (baud rate, etc) from the epson lx300+ii and the epson lx300, it's all same settings. Printing using windows has no problem, but I need it to print using a DOS based program. Have you encountered similar problems? Is there any explanation and solution? Thanks.

    Sorry Benson, but I'm not using XP, I'm using a DOS (MS-DOS) based program, and usually there's no printer driver for it, we just plug it, and it works :)

    Actually I've tried to make my own serial cable, and it seems work, but I'm not sure if it function properly, because I connected a loopback from the computer back to itself, so no error message can be sent by the printer.

    But I'm still curious what's the different between epson LX 300+ii and LX-300+ that can cause such a fatal disfunction? Perhaps there's someone know something? :)

    Thanks anyway, Benson, Keep up the good work.

Use the com1, and use a baud rate like 9600, with 8 and 1 bit stop. dont. be sure that is in ESC/P or IBM as you requiered. if your software use directly the serial port, be sure that the bios set up is properly. i think that the lx300+ have less buffer than lx300+2
and if you use high speed, could loose info.

Hi there,

Just a couple of questions that might help your problem.
- Have you already installed the driver of your lx-300+ ii?
- Are you using that driver for your lx-300+ ii printer?

XP as far as i know does not have an Epson lx-300+ ii driver.
And yes, it only have the lx-300 & lx-300+.

Using backward software (i mean, using the lx-300+ driver
for your lx-300+ ii) is possible but not advisable.

My problem is im using a laptop, in my printing is EPSON LX300, what would do to make it run?

You need extra USB to Parallel device.
If you bought LX300 without USB interface you need this device... The USB port will be attached to your laptop and the Parallel port will attached on your printer parallel interface.

It looks like this, cost about 4$-10$ee99399.jpg

Serial meaning 2.5mm stereo headphone looking jack to DB9 or "atari joystick" looking plug? I had one on my first Toshiba PDR-M1 camera but that was like 9 years ago. You can probably find the pinouts online for that cable, I believe it is a standardized cable.

The stereo plug is wired to the PC serial port as shown in the following diagram:
tip ring sleeve +---------------------------------+
| |
/-------+-----+--------------+ |
| RxD | Gnd | TxD | 2.5 mm Stero Plug |
\-------+-----+--------------+ |
| |
DB9*: pin 2 pin 5 pin 3 +---------------------------------+

DB9*: Optionally short together pin 4 (DTR) to pin 6 (DSR) and
pin 7 (RTS) to pin 8 (CTS)
The following table also describes the camera cable's wiring: Camera PC's
Plug DB9* Signal Name Direction
---- ---- ----------- ---------
- 1 Carrier detect (CD) input to PC
tip 2 Receive data (RxD) input to PC
sleeve 3 Transmit data (TxD) output from PC
- 4 \ Data terminal ready (DTR) output from PC
ring 5 | Signal ground (Gnd) -
- 6 / Data set ready (DSR) input to PC
- 7 \ Request to send (RTS) output from PC
- 8 / Clear to send (CTS) input to PC
- 9 Ring indicator (RI) input to PC
* Note that the cable's D-subminature DB9 RS-232 serial port connector is female. This connector also goes by the historically more correct name of "DE-9J".

Printer not Print data in English Language

Hi, you may want to reset/restore the Epson LX300 to default settings. This can be done by pressing down on the FONT button while powering on the printer. If done right the LX300 will print a test page with the firmware version. It is also possible that the drivers are corrupted. In Start, Printers & Faxes, delete the LX300 printer, restart your PC and then re-install via Add Printer. In some cases, defective parallel cable can also cause problems. Unfortunately the only sure way of checking is by replacing the printer/parallel cable with a known good/operation cable. If the printer would really be requiring service, a Service Manual is available at ( Hope this be of some help to you. Good luck and pls post again how things turn up.
