This printer operates fairly fast with excellent print quality. The only real problem is the screen being entirely too small to see without a magnifying glass. The 1 year free HP Instant Ink is very worthwhile. The Instant Ink system is rather slow and the post office takes forever to deliver a cartridge.
I bought this printer after the HP 8610 I had for many years stopped working. The 8135 seems to operate much the same as the as my 8610 did and has all the same features. So far, the printer has functioned flawlessly.
