We are going to write our review on two commercial printing calculators, one with printing on paper and the other with new technology (paperless printing model). Both calculators are made to work in the office and to do hard work. They work great, but in totally different ways.

First model Sharp EL-1901 Paperless Printing Calculator uses brand new technology – simulating printing job on the big LCD.

The other one CATIGA CP-30A Commercial Printing Calculator is using a printing paper rolle to print on.

Sharp EL-1901 Review

Not using print paper is the main advantage of this model. Sharp EL-1901 is using LCD technology, combined with memory, to store your work. Paperless printing calculator is efficient, environmental friendly and saving.

Print on paper vs paperless printing

On this topic we have compared 2 office printing calculators. One standard, using printing paper rolle, and one with paperless technology. Both printers, Sharp EL-1901 and CATIGA CP-30A, bring us commercial printing and office calculations on the working desk.

One uses a classic print paper rolle, while the other one comes with paperless design and technology.  

Sharp EL-1901 has a higher starting price, but you must consider that you won’t buy any paper through the printer working period. Sharp model EL-1901 is more cost efficient and environmentally friendly. Only disadvantage for this model is that you need to adjust and learn how to work with printer calculators who actually don’t print.

CATIGA CP-30A is a good machine for its purpose. Nothing special to point out, except maybe 2 color prints. Mostly these commercial printers work with one ribbon and one color print.
