Unable to print to HiTi 630PS

[Paul]

> I have installed HiTi 630PS USB printer per manufacturer's instructions, using connection  usb://HiTi/630PS 630PS.ppd provided by HiTi.
>
> When I attempt to print, after several seconds the lamp on the printer will blink, its drive motor is operated (for just an instant), then nothing. Some moments later, the job will appear in the "completed jobs" list, appended "Unable to write print data: Input/output error"

try either printing with the -o raw option or switch to the raw device type and lp a text file to it.  see if that prints, that will point you in the direction of if the printer is flushing it or not.
