Driver Epson Tm T20x

[Etienne Levic]

Idid the installation of the printer, configured it and printed a word file, it printed all ok, printed until where there were no more characters, but when I try to print from web, a huge blak space is printed along with the document. I tried in chrome, safari, ie, firefox and opera to see if the problem was with the browser, it wasn't.

About the epson documentation, i found very few things that would help. All the mocks are problematic, doesnt work, the same goes for the code examples and eclipse projects that it is available in their example page.

You should have to make any adjustments on printing!, You install the driver and PRINT! Page size and header and foot should be left alone. Do all of your printing for margins INSIDE YOUR PROGRAMMING and from there you should mess with it, setup how your layout is and be done

Thank you Chris for the quick answer. I am at a loss now. What can I do to make it print. In the document it says using

Printer: epson (instead of printer) - Mode: file - Port: dev/ttyUSB0

and "... several receipt printers manufacturers provide a system module for Linux that creates a device file like /dev/ttyUSB0 when the receipt printer is connected to an USB port."

This is where I am stuck, I don't know how to create /dev/ttyUSB0 and I can't find any "system module" doing that in the EPSON website.

I google about /dev/ttyUSB0 and it seems that it requires a "USB 2 serial" converter. WHat is that? Is it another piece of hardware that I need tobuy? Or is it just a software module that I need to install?

there's no driver installation necessary, just use the epson config option. You can find out the required com port settings by pressing the "feed" key of the printer while turning it on. A receipt of the needed settings will be printed out immediately.

have you try to print to /dev/usb/lp0 or /dev/lp0? you can try this as root (sudo echo "test" >> /dev/usb/lp0) if this works you just have to configure unicenta to print EPSON driver and print to a file /dev/usb/lp0 , your user must be on the lp group to have write permissions

Sign in name is the name you use to sign into your system. After you have done that, I know it's not windows but you have to log out and back in or restart system so linux can pick that new setting up.

Fabian, above in my one of my responses will explain how to do it... Follow the steps first then test. I tested on my current POS system running Ubuntu 13.10. Yes I was used to the root superuser too and have to learn there's no root and DO NOT ENABLE IT.

Otherwise follow my steps above and test with the guys steps to test and you will now have a running machine. NOW to apply that to your software...

But another day. I tried to print and the printer was simply not cutting the page, then sometimes it print or sometimes not (always whitout cutting the paper) and CUPS web interface tells me that the Job has been finished. Sometimes prints garbage. Then I change the cable serial to USB, but nothing happens.

because the readme of the epson driver says that the driver has been tested just with that version of Ubuntu. I added just an aditional information. I will edit my question to make things clear, sorry.

Finally after a lot of pain. I discover that the problem was the serial to USB cable (in order to connect the serial printer to an USB port). I tried with two different serial to USB cables, but the problem persists and finally I conclude that The printer works erratically if is not connect to a "real" serial port. I tested the printer under identical conditions in a PC with a serial port and it works perfect, just installing the driver provided by epson and giving chmod 777 to /dev/ttyS0. At the job list sometimes I see the error: "/usr/lib/cups/filter/pstopdf failed". But the printer prints ok, like no error occurred.
