I have two HP printers - one inkjet and one laser. Both load paper from front. Both have wireless connectability. As for front loading paper, I think back 20 years and have never had anything but a front loader except for the old dot matrix using roll paper.
All in one means a scanner and copier built in. Material to be copied or scanned probably loads under the lid or on top - but the target paper should be in a front loading tray or drawer. Front may depend on how the machine is positioned on the table.
Do you have some sample machines to consider?
