自定义工程VKP80 - 在linux上打印根本不打印任何东西

Question

为什么Linux无法打印到打印机型号：Custom Engineering VKP80？

$ lpstat -p -d
printer CUSTOM_Engineering_VKP80 is idle.  enabled since Sat 05 Apr 2014 10:50:52 PM CEST
printer LabelWriter-450 is idle.  enabled since Tue 25 Mar 2014 10:47:06 AM CET
printer PDF is idle.  enabled since Tue 25 Mar 2014 10:40:12 AM CET
printer Zebra_TLP2844 is idle.  enabled since Tue 25 Mar 2014 05:52:37 AM CET
system default destination: LabelWriter-450

$ echo 'test' > /tmp/test.txt
$ lpr -P CUSTOM_Engineering_VKP80 /tmp/test.txt

什么都没发生。
