I’d say 7 to 10 business days. I’ve seen as much as 2 to 4 weeks as well. I have a C&P 10×15 and at first it took forever to do things- set up, inking, printing,etc. The longer you work on them, the more proficient you become. If you have items that you want to print for yourself, or to sell, I would time yourself from start to finish and see how long it takes you to get those done. I know you said that you usually print 2-4 hours, for me in the beginning, it took me that long just to get one design running on the press. Now I can do a couple of designs, same ink color, from set up to finish in about 20 minutes each depending on the run (just did this for 100 circle monograms and 100 invitations). Again, she’s motorized and has the ability to run on a treadle, but I’ve run her on the motor. I hope this helps!
