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. There is no warranty that the amount of datas will be a factor of 64 bytes.help
