Roland, Mimaki, Mutoh, HP
i would suggest printer and cutter separate. You will also need a laminator for decals.
30" is OK, but I would go as much as you can, 54 would be ideal.
I have bought used Mutoh 48" and new Graphtec cutter FC 860-130 (54").
Will be looking for new printer at the end of the year on next year.
Maybe I will go with HP, they do not have as many issues with the maintenance of the printheads. Every solvent printer needs to be printing every day, latex can be down for a few weeks with no problems.
