=====  LabelWriter 315 =====
====  How do I set the resolution? ====

Use the pbm2lwxl tools.  Set resolution to 300dpi.
====  How do I make this printer work with USB? ====

You need to make a small modification to the USB driver.  These
steps were reported working.

1.  Unpack linux-2.4.20

2.  Change to **''/path/to/src/linux-2.4.20/drivers/usb''**

3.  Edit **''printer.c''**

4.  About line 880, there's the detection code.  There's a check to see
if the transfer type is 'bulk'.  I just commented out this check. Note
that according to the USB spec that I read, the 315 violates the usb
LP protocol:
Before:
<code>if ((epd->bmAttributes&USB_ENDPOINT_XFERTYPE_MASK)!=
 USB_ENDPOINT_XFER_BULK)
 continue;</code>

After:
<code>/*if ((epd->bmAttributes&USB_ENDPOINT_XFERTYPE_MASK)!=
 USB_ENDPOINT_XFER_BULK)
 continue; */</code>

5.  Configure/compile as usual.

====  What are the known problems? ====

There are some white lines in some output.  Barcodes worked fine,
the text below showed some white lines.  It should be fine for labels.
