I have an HP Officejet v40xi 4-in-1 machine. The printer works very slowly, i.e. it might take 5 to 10 minutes for it to print a page. This occurs when I use it alone and when I send it a print command. Please render some technical advice on what my problem might be. Thanks for the help.

Unfortunately I can't offer any "technical" advice on this problem, seems to be printer hardware related. But it seems this old printer has it share of problems. Like here and here.

Perhaps its time to move onto a new one. The price of a printer is really cheap now anyway, especially when on sale.

As an example, I had a HP 990cxi. The inks cost $90 cdn! For an original black and color. I could buy a new inkjet for 49 bucks instead.:)

I did try the ink refills, but the quality was not acceptable to me.

When I went shopping for one, I looked at the inks first, see which were the lowest prices, Canon and Epson are pretty good, then I checked which models they were compatible with and bought that model :D
