As mentioned previously using LinuxMInt on i Mac; using a HP P1005 usb laser printer, which until 3 days ago functioned perfectly.
It printed about 30pages this morning; after tat I turned the printer off; this afternoon no printing function.
In terminal I typed dmesg with many lines of out put. The relevant ones are shown below

I take it usblp0 identifies the printer.
According to the control centrer the printer is recognised; however when booting the printer remains deadly silent, which is normally not the case.
