Serial Printer & Serial Customer Display. NV UTIL.

[emagnews]

Hi,
I have a serial receipt printer - epson tm-t88iii (i know!) and a serial customer display. The customer display plugs into COM1 and the printer into COM4. I have Windows 2000 on the PC. On boot - while loading windows 2000 - the printer prints out about 4 lines of random characters and the customer display displays about the same amount of the same data. Is there anyway to stop this - it makes a mess of the first receipt of the day?

Also - after it works perfectly fine. I have been trying to upload a logo to the printer via the NV Logo utility but it cannot seem to recognise the printer on COM4 (and have tried every other COM port). Any ideas?

Thanks

Could you give me some info about the pc ie make, model and did you load the drivers for the printer.

Also could you trun off the printer and hold down the paper feed button and turn on and give me the info for the items below

Baud rate:

stop bit:

party:

flow control:

Info this info help me a bit.

also are you using USB to serial converters

Hi,
Currently using eMachines 360 - running windows 2000. Not using usb to serial converter.
Baud: 19200
Stop Bit: 8
Parity: 1
Flow Control: DTR/DSR

Drivers are loaded correctly - from official epson website.

Thanks

You are have to try this.

by default you com port works at 9600.

You are going to have to trun off the printer and unplug it from the power.

trun it up side down and you will see a small metel plate. Open it

you will see two groups of switches. The ones we need to change are in the group 1 (the group should be marked DW1 or SW1) and it will be switch 7 in that group, turn this switch on. This should brung the baud rate down to 9600 which should stop your problem.

you can test this to make sure that you turned on the right switch is to plug in the printer to the power and hold down the paper feed switch and switch on. the baud rate should be 9600 now.

this also should fix your problem of not being able to upload a logo to the printer.

Great, thanks. Will try it when i get back to the shop. Will it be the same fix for the customer display - 9600 baud? Or is this just a windows 2000 problem?

Thanks
