I've never operated a dot matrix printer before but I first notice that the top tray of my Oki Microline only takes one page at a time (can that behavior be changed?). It won't affect the project invoice printouts because I'll be using continuous form paper fed from the back. Also it seems not to like a second print job with both print jobs being from the top tray, unless I power off and on the machine again. (It's a native USB Microline 421). Maybe the printer is on its last legs, or more likely I haven't figured out the machine yet. It's on Windows 10 (!) and I've tried the Oki driver built into windows as well as the generic text dot matrix driver also built in (the latter uses the Oki's internal dot matrix font which I like). As the resident dot matrix expert, what would you recommend?
You can have first choice with the M122's without keys and inserts. $8 each if you want them. They require Soarer's converter to work with a PC. They are very dirty but the springs are not rusted from what I can see. 3 are the first gen/larger cases from around 1989 and 4 are the smaller cases from ~1990. I also still have the M101 parts boards, now reduced to $15 ea.
Glad to hear the site was online ahead of schedule.

It's always hard with projects like these (or even projects of any sort) to have hard time deadlines that actually stick. I'm glad you're hitting your targets because that makes happy campers!
Hmmm...I have 320s, which are the predecessors to the 421 series. There really aren't 'trays' on dot matrix printers--just the platen (like on a typewriter) and the paper feed mechanism which can be selected between friction feed and pin-feed. Since you have the continuous paper (and I'm assuming you've got a box of it so 500+ sheets), just load in the continuous feed paper first and see what that does.
If you're using a single sheet (non-pinned paper), then that's expected behavior as the printer's buffer would have all the information and its just waiting for another sheet. But there's also a lever I believe on the right side to change between plain paper (friction feed) and pin-feed that also adjusts how the printer works in relation to continuous printing. I'll have to look at a 421 manual to really know what's going on.
But windows 10 and usb is going to be tough. You're going to be fighting 2 decades of computing progress to get that thing to print plain text natively. The good thing about these dot matrix printers is that they essentially just need a text file sent to them and they'll print it. So that's the challenge.
What I would try is putting in continuous feed paper and run the printer self-test--that will let you know the printer is fine (which I believe it is). Next, open up notepad or some other plain jane no fancy pants text editor and have it print to the printer. A plain text editor outputting plain text should be able to give the printer what it wants. It should print extremely fast for a dot matrix (570+ cps spec on that thing is crazy fast--300+ was fast back in the day). If it doesn't, some sort of system fonting/truetyping is going on and the printer's native font isn't being used (which is what you want). Then we'll have to try some other methods.
Thank you for the first dibs on the M122s. I have yet to have my soarer cable come in, so let me play with that first and see how I like it before getting with you about an order.
