In general, no. You can be dot-aligned but most printers will take a 300/360/600/720dpi image and upscale and dither it to a higher resolution with the corresponding colors and dot sizes.
If you generate a printer-specific language like PCL or ESC/P, it is possible to send bitmap graphics (or in the case of many Epson printers, 2-bit per color graphics) that are not altered by the printer, but this is very printer-specific.
