I'm going to throw out an idea in a different direction. I'm keying off part of the description in the original post -- "When I say 'cross hatching' - if you look closely at the sky ( lighter area ) of the print there are many, little boxes formed by both vertical and horizontal lines."
If the bad prints have a uniform cross-hatched pattern across a large area (or the entire print -- it's unclear), to me this does not signal a mechanical paper feed or head alignment problem, or a physical ink lay-down problem. All of those issues create what I would call a banding pattern -- parallel lines running either with the direction of head movement or with the direction of paper movement. None of those issues by themselves would create a cross-hatching pattern composed of both horizontal and vertical lines. It would take at least two separate printing faults combined to create cross-hatching, e.g. both a paper feed issue and head alignment issue, or both a severe nozzle clog affecting multiple ink channels plus a head alignment issue.
As a trouble-shooting approach, I tend not to assume that 2 or more separate problems both suddenly started to happen at the same time. Assuming the printer was actually working previously, then if there's a single root problem that has started happening, it needs to be capable of creating the observed effects. In my experience, actual cross-hatching is not caused by the printer, but most often is a digital artifact triggered by something upstream of the printer.
Having said that, I'm with Mark in pointing out that we really have too little info to diagnose much -- we don't know what software is making the prints, any of the software settings, the driver settings, or anything about how the problem file(s) have been prepped for print. From the posted print scan, I can't really see what's going on to any degree of detail since the file is very low res. I don't know whether the heavier lines visible in the scan are parallel to the direction of paper movement or head movement. With little info, we're just speculating about possible problems & solutions.
Beyond just posting a ton of details, I could suggest some basic trouble-shooting for the OP. For example, print a standard reference / test image on the same paper with the same settings, and see if it comes out clean. If the reference image has the same problem, then something with the printer or the print settings is wrong. But if the reference image prints clean, that likely rules out anything with the printer itself or the major print settings in which case we need to look more closely at the problem image(s).
If basic trouble-shooting doesn't isolate the issue, then to follow up here there's really a bunch of info we need. What file resolution do the problem images have, and what software edits have they been run through? Any plugins to do with heavy noise reduction, contrast enhancements or upscaling? More generally, what software is driving the printer, what are the print software settings, what are the driver settings? What is the media type, what is the platen gap? Etc.
