RAM
The amount of internal memory installed in the printer.
The main purpose of such memory is to store tasks sent for printing. This gives various additional features: printing when the computer is turned off, continuing to work after troubleshooting, pausing the process and resuming at will, etc. The more memory, the wider these printer capabilities (in particular, large volumes allow you to store more tasks ).
Note that we are talking about the built-in memory; if the printer also has a hard drive (see below), its capacity is specified separately.
Noise level
Approximate noise level generated by the printer during normal operation. The decibels in which the noise level is expressed is a non-linear value, so it is easiest to evaluate this indicator using comparative tables. The
quietest printers give out about 35 dB — this is the volume of a conversation in a whisper, such noise will not stand out even in a quiet library reading room. A volume of 40 dB approximately corresponds to a conversation at an average volume, according to sanitary standards, this is the upper limit of permissible constant noise in residential premises during the day. For offices, the border is slightly higher — 55 – 60 dB, this is the volume of a conversation in raised tones. And the most powerful and heavy models give out up to 70 dB — this is comparable to a noisy city street; if such a printer is planned to be used frequently, it is advisable to install it in a separate room.
In general, lower noise levels make the device more comfortable to use, but may affect performance and/or price.
Power consumption
The maximum power consumed by the printer during operation. The lower the power consumption, the less energy the printer consumes, the more economical it is. On the other hand, devices with lower power consumption are often less performant than their more high consumption counterparts. And for the same performance, a more economical printer is likely to cost more, but with heavy use, it can pay off in energy savings.
