I began using a Canon printer. One B1 and two A1 photos can be printed on B0 paper at the same time.
I threw out my 10-year-old Epson printer PX10000 and bought a Canon B0 model. I can now print 10 sheets in a few hours. With the Epson, printing would take all night, so it took courage to hit that print button. Now, I can get everything done in a few hours with no trouble. I imagine that Epson has improved since then, but the Canon was cheaper.
All I need to do is send the data from photoshop and it prints. It feels great to have this basic process go so smoothly. Compared to a few years ago, it’s gotten a lot more expensive to outsource. If you print 100 sheets, then this printer practically pays for itself.
