After trying several brands and models of laser printer, the printer I have settled on is the Lexmark E260. I use it because:
1 – It has an excellent Local Printer Utility that allows almost every printing parameter to be adjusted.
2 – It is readily and reasonably available on Ebay or Craig’s List. I paid $45 for each of the last two I bought on Ebay, including shipping.
3 – The drum is separate from the toner cartridge and is relatively inexpensive (<$30), so it can be replaced if it does become damaged.
4 – The printer has a manual feed slot in front so the paper path can be “flattened” with reasonable effort to pass PCBs.
5 – The charge on the drum seems to provide for essentially perfect transfer of toner to grounded metal sheets.
