Laser printer manual duplex printing
Solution 1:
I've ran into the same problem. The solution I had to do was print in smaller page ranges, and when I reinserted the paper to fan the paper so the pages wouldn't stick to each other. I also monitored the printing so if the pages did jump, I would manually get the pages back on track and just reprint the few bad pages.
Ultimately, I got a printer that duplexes, and it was worth the money for the duplex feature.
