I have never seen this issue before with SambaPOS.
Can you load the logo into the printer and then call it in the printer template ? This will bypass the need to send the logo to the printer each time.
If the problem doesn’t come back I would look at a communications issue with the printer.
I need it to happen again so I can determine if its the from the same position.
It is connected via USB and we sometime lose connection to the printer for some bizaarre reason and we usually restart the printer. (Unreliability of USB?)
@Isaac, if your having connectivity issues, then that’s the problem.
If it runs on a COM port, try dropping the speed.
Also fitting a ferrite core like http://bit.ly/1cYhqXC may help too.
And this is the printer I currently use http://bit.ly/1oTjJuT
As I have said, it’s not the fastest Epson ever made, but it has a lot of features, works out of the box, and supports Win8 64bit. We have had no issues at all with reliability.
PS - the link shows the serial version. Couldn’t find a usb version available In the UK.
