At some point in the future I hope to do a column on general tech support issues. I wish I could cover highly-specific, individual items like this in the column, but unable to myself. Perhaps other readers here can chime in.
I have a HP910 colour printer. Though I have done all tweaks to see the gridlines in colour(I love light blue lines)I get them printed only in black. Previously I had an Epson inkjet with which I got them printed in colour. On interacting with the HP service they accused the software 'Excel' as the culprid, and not the printer' Please help me.
