Could you verify that, that cups > is feeding too little data into the ULPT port? Sometime cups writes only a litle amount of datas: [Job 40] Read 161 bytes of print data... [Job 40] Wrote 161 bytes of print data... [Job 40] Read 251 bytes of print data... [Job 40] Wrote 251 bytes of print data... [Job 40] Read 162 bytes of print data... [Job 40] Wrote 162 bytes of print data... [Job 40] Read 86 bytes of print data... [Job 40] Wrote 86 bytes of print data... [Job 40] Read 3292 bytes of print data... [Job 40] Wrote 3292 bytes of print data... [Job 40] Read 43 bytes of print data... [Job 40] Wrote 43 bytes of print data... [Job 40] Read 4096 bytes of print data... [Job 40] Wrote 4096 bytes of print data... Cups uses a select() on the input file to print, reads the datas and writes them to the usb port until the input file is empty.=20 There is no warranty that the amount of datas will be a factor of 64 bytes.
