The XGP was 200dpi; the third generation Dover printer (used, e.g., at SAIL)
was 384dpi, but the SAIL fonts were 200dpi.
My own first experience with laser printers was the Xerox 9700, based on a much
higher quality Xerox copier engine than the XGP/Dover. It was 300dpi, had dual
print engines so that duplex was a fast as simplex, and altogether a beast. We
attached it to an Amdahl 470/V7 running SVS (= OS/VS2 v1), then moved it to the
3031 running MVS when that came in.
I did my printing from the DEC-20s over an RJE link to those boxen.
