It's funny how all of you HP owners say this printer is the best and you never had problems with it, but on the other hand at some point after your purchase have complained about something, from errors, to material curling, to material shrinkage, burning, RIP problems, ink drying, new printheads not working properly, and thanks to BigFish if he wasn't MM here you would still be looking for compatible materials for this printer.
I've gone from three Rolands to three Latex Machines.
Had a SP540V, XJ640 and still have an XC540W.
I now have 2 x L25500's and a L26500.
I've had no more issues with my HP's then I did with my Rolands.
If your a small sign shop and print here and there yes the Roland is better. Less warm up time, easier to load can have print and cut. The Roland also uses less power.
But if you're doing anything with volume the HP wins hands down. Faster speed, less ink consumption, can use prints straight off the printer, cheaper then the Roland even factoring in heads, cleaning cartridges and even the over priced waste container.
I say less ink consumption based on our real world usage.
Here locally the reason why we even looked at HP was because the service we got with Roland wasn't what we expected. Being down a week for a tech to come out is unacceptable in our situation when its under warranty. With HP as mentioned earlier next business day support.
The new pro 4 are still eco-solvent. Single head configuration. Faster, better quality then the pro 3 series.
