[CUPS打印机正在使用中

Question

我最近在Debian Linux 9中添加了一些打印机。每当我尝试打印到其中任何一个打印机时，CUPS都会报告“打印机正在使用中”。这从lp命令和CUPS Web界面都发生。这是我的一台打印机的配置：

<Printer IT>
UUID urn:uuid:04d3f4a4-aa59-3760-6bcc-8c7383edae70
Info IT
Location Office
MakeModel Lexmark X658de
DeviceURI lpd://192.168.1.60/IT
State Idle
StateTime 1553021794
ConfigTime 1553021782
Type 8425692
Accepting Yes
Shared Yes
JobSheets none none
QuotaPeriod 0
PageLimit 0
KLimit 0
OpPolicy default
ErrorPolicy retry-job
</Printer>

我可以远程登录打印机。我的cupsd.conf文件如下所示：

我在另一个Debian盒子上安装了这些打印机，它们工作正常。我对此一无所知。

我意识到这个答案不能解决OP的问题，但是我遇到了同样的错误。因此，希望这对以后的人有所帮助...

我的问题是我的打印机墨盒之一是空的。更换空墨盒已停止，显示“打印机正在使用中”错误，并且文档立即打印出来。
