I think there was also the 1515, with only 6 inch wide paper, not the normal
8 inch type.

It has nothing in common with the 801/803, it is directly based on the
parallel CBM printers. The direct equivalent is the 4023 (though I have no
idea if the 802 is based on the 4023 or vice versa), which has many features
and commands in common with older printers as the 3023. The first printer
must've been the 2022.

These printers lack a proper bitmap graphics mode, they have only one user
definable character. Many C64 programs used this to print complete bitmap
graphics by sending 80 newline charcters per line as well ;-) I adapted this
idea to the 3023, but as this printer was already old when I got it in 1987
or so, the result looked very ugly. It also took about an hour to print a
320x200 bitmap with that 7x6 matrix.
