How do I stop my computer from putting the printer offline on its own? -

It will say it s ready and printing fine one minute and then it puts itself offline and I have to put it back online and reboot the pc in order to get it to print again.

I found this KB article on microsoft website. Your USB printer is listed as offline http://support.microsoft.com/?kbid=83446… hope it helps

not sure that your PC printer settings will set your Printer offline. Reckon this must be some powersave on your printer, check your printer manual.

Reinstall drivers.

pls check your printer settings and reinstall printer driver try to select pcl or postscript on the printer driver
