Printer problems... Hi, I purchased a 2nd hand Epson TM-L90 printer and I'm having some problems with it, I've also just purchased the correct serial and power lead and was supplied drivers for the printer. After installing the Epson Advanced Printer Driver and printer doesn't printer on command, infact it only prints loads and loads of pages of ???????????? this only happens when I restart my PC, very weird. The printer is connected to my PC from serial to serial ports (25 pin) I have also tried to change the setting from different ports but still without any luck. Tried to testout the 'Print Test Page' in CP under printers but yet again nothing happens, not even ???? Does anyone know anything I maybe doing wrong? Any help or helpful advice would be most appreiated. Pete

Have been looking through the manual (sorry no link to it - you have to register with epson as a service contractor to get it). There is no reset as such, but there is a list of DIP switch positions;


switch 1-1
Power switch function
on=Disabled
off=Enabled
1-2
Interface condition selection
on=by DIP switch
off=by memory switch
1-3
Handshaking
on=XON/XOFF
off=DTR/DSR
1-4
Data word length
on=7 bits
off=8 bits
1-5
Parity check
on=Enabled
off=Disabled
1-6
Parity selection
on=Even
off=Odd
1-7 and
1-8 (in order)
Transmission speed
on/on=2400bits per second
off/on=4800bps
on/off=9600bps
off/off=19200bps
switch 2-1
Reserved
Fixed to Off.


If 1-2 to 1-8 are all set to off, then the printer is set up for parallel printing which could conceivably be the problem.

Try one at a time in a different position and see what you get. It is slightly unclear on the location of these DIP switches, but i believe you get to them through the base - just pull the end with the cable holes away from the printer and it should snap out (probably worth checking in the top first in case they are obvious)

If you need more help with this then please ask again - I will keep hold of the manual until i hear back from you, there is little else of much use in it, and nothing that sheds any other light on the problem - I think the DIP settings should help, just make sure you write down what they are set at before changing anything.
