Re: [Epsonepl-users] USB support for EPL-5800L, any good news ????

[M. M. <mm...@ya...>]

I just tried the 0.2.2 driver, i didn't get any improvement yet. The printer
remain silent and didn't respond to the commands. I tried both the ./ps2epl
xxx.epl > /dev/usv/lp0 and ./ps2epl xxx.ps /dev/usb/lp0 without success...

Did the same with Mandrake 9.0 (installed on another partition) however, i
get the same result. The problem seems not related to distributions.

I'm open to suggestion. Thanks.
