帮我看看我的打印机3848阿
谁驱动了HP DeskJet 3848?我用了hpijs中的3845,3840,能够辨认出来，可是不能打印任何东西，没有反应。
探测的结果都正确识别是3848，就是不能驱动，也安装了hplip,可是还不行，实验了hpoj,结果运行ptal显示
Probing "/dev/usb/lp0"...
*** Found "Deskjet 3840" but failed to communicate with it!
*** Elapsed time for this attempt was 0 second(s).
*** Check syslog file for ptal-mlcd error messages.
*** See hpoj documentation for troubleshooting information.
而cat /var/log/message |grep ptal-mlcd显示
