Sometimes it makes sense to decide on the side on dependability and/or support. Which ever is more likely to last and/or seems to be the leader, get that one. If the needs are robust then pick the one that seems is going to last. Since this is a business decision and one you may depend on an extended time, don't settle on cheaper cost or entry level devices. Maybe get the lesser cost then within a 1yr. or sooner the more desirable one. However, if you'r really going to take it to task, get the sturdier model, etc. Also, look at any s/w demands which may from its menu place the selection more easily rather than any special or unique specs, etc., like needed s/w bundle. You may want to cjheck "used" market and see what appears more available plus it doesn't hurt to check the HP support website, what common issues are noted for each model.

My company is a small Architectural firm with large scale projects. So we need a plotter. we decided to go with HP 111 24" or T120 24" (eprinter CQ891A). Which one is better?
A vender suggests HP 111 is better than HP T120 as T120 has delicate body.
Note: HP offers stand along with t120 but not with 111
