Hello, my name is Syd and I am with Epson America
Usually this type of counter appears in a laser printer where one page is a 'cycle' and the page size is almost always the same. With an inkjet printer there is usually only enough memory in the printer for one line of print. When this is full, the carrairge will print that line, and the computer will send another line.
Because of the many different paper sizes (4x6, 5x7, etc) and quality settings, (draft, text, economy, photo, etc..) one single page would not show how much the printer has been used. For example, Showing the printer has done 100 pages would give very little meaning as you would be more interested in if these prints were 4x6 photo, letter size text/image brochure, or a high resolution 13x19 borderless print. Because of these great variables, photo inkjets usually do not page counters.
We do have certain workforce Pro series models that are designed to replace laser printers. As these models are 4 color made for text/image letter/legal size only, there is a page counter on those models.
