You can do tiled printing easily in Photoshop, using a manual technique. I have done several tiled prints that turned out nicely. Photoshop has all the tools you need.
The key is to set up a custom grid that corresponds exactly to your tile size, or a simple multiple of it. For 8-inch tiles your grid could be 8, 4, or even 2 inches. Since I have a letter sized printer, my tiles have been either 8x10 or 8x8. I have come to prefer the "look" of the square tiles, but there is nothing to keep you from using various tile sizes. For 8x8 tiles, I set the size of my Rectangular Marquee tool to my tile size. For precision, I prefer to work in units of pixels. I print my tiles at 240 pixels per inch. Then use the Rectangular Marquee to cut a tile like a cookie cutter and print the tile. The Marquee snaps to the rectangular grid for effortless pixel-perfect positioning.
Reload your master image, select another tile and print it. You will need a rotary cutter and an appropriate straight edge for precision trimming of the tile prints to get a good "seamless" assembly.
I will provide more detail in a subsequent message. But Photoshop is definitely up to the job.

Here is some more detail. Several years ago, in the CompuServe Photography forum, Jonathan Sachs of Digital Light & Color, Inc., in a series of messages, introduced me to tiled printing as a technique to escape the size limitations of my Epson Stylus Photo printer. His Picture Window program supported tiled printing even back then. The Digital Light & Color website is:
However, I developed a manual technique for tiled printing in Photoshop, using Photoshop's custom grid snapping with a fixed size rectangular marquee to cut a large master image into pixel-accurate tiles. Laminating the tiles made them easy to handle and a rotary trimmer, with a nonslip rule and a self-healing plastic cutting board, enabled pixel-accurate trimming of the tiles.
I have since been doing tiled printing with my venerable letter-sized Epson Stylus Photo printer and Photoshop. Most printers can't print to the very edge of the paper, so the actual size of the trimmed tiles will be something less than 8.5x11. My first tiled print was made of four 8x10 tiles. I then decided I would prefer square tiles, and went to square 8x8 tiles. I prefer the look of the square tiles, but for some pictures I might use smaller tiles. For example, if I were doing a 25" x 30" picture, I would probably use 5-inch square tiles. A 24" x 32" picture could use 8-inch tiles. I use repositionable mounting wax, although I rarely need to reposition a tile because lamination makes them easy to snap accurately into place. Precision trimming and placement make the seams nearly invisible. Details of the tiled printing process are as follows:
First create a large print-quality image in Photoshop. I usually use Genuine Fractals to help me do that, but that is optional. The pixel dimensions and file size of this "master image" will be large, and challenge your RAM and Scratch Disk resources. Do all of the image processing you need to do before cutting up the master image into separate printable tiles. Originally I tried for a small "overlap zone" between tiles, but I found that to be more trouble than it was worth. I now cut my tiles in Photoshop to fit flush, and precision trim the prints using a handheld rotary cutter, a non-slip metal rule, and a self-healing plastic cutting board.
Warning: Any processing you do to the individual tiles after they have
been cut in Photoshop is liable to cause visually detectable differences
at the tile boundaries. It would be nice if you could upsample the tiles
to make them bigger and allow the master image to be smaller, but the
human eye is remarkably capable of seeing subtle differences at the boundaries.
So far, all of my experiments with upsampled tiles have caused noticeable
boundaries.
The pixel dimensions of the master image should be integer multiples of the pixel dimensions of the individual "tiles".
Set Photoshop's grid spacing equal to a single tile dimension, or a simple fraction of it. Set the Rectangular Marquee equal to the size of the tile. Save the Photoshop "master file" at this point, because you will be repeatedly re-opening the "master file" in the following.
Turn on Grid Snap and use the Rectangular Marquee to select the upper lefthand tile (it will snap right into place.) Image-Crop to discard everything but this tile and Save As some meaningful name like "Tile_1_1.psd" and then re-open the "master file" and select another tile, Image-Crop, Save As "Tile_1_2.psd" and so on. In these sample filenames, the first number is row number and the second number is the column number of the tile "matrix". This technique produces tiles with pixel-perfect accuracy and their names tell you their position in the final image (although you can usually figure this out for yourself.)
After you print all of the tiles (one tile per page), you have to precision trim them and mount them on a suitable support (foamboard, mat board, masonite, plywood, wallboard, or whatever). The details of that are another story. With a lowly little inkjet printer you can create some really big pictures.

If I understand you correctly - you simply want to print out at A4 size. If
this is the case print using the 'Print with Preview' option and simply
scale the image to fit on your paper.
