Print formats
The largest paper size that the printer can handle. Most often, the formats are marked from A0 to A10; it is from here that the famous “A4” is taken, denoting a standard landscape sheet. Modern printers can use the following formats:
A2 — 420x594, the size of a newspaper spread. The largest format used in today's consumer-grade printers. In fact, this size is rarely required, and the printers themselves are expensive; therefore models under A2 are usually high-end professional devices.
A3 — 297x420 mm (2 times larger than the landscape sheet, magazine spread). It is mainly used in the business area for printing large letterheads, brochures, announcements, posters, etc.
A4 — 210x297 mm, standard landscape sheet. The most common paper size for home and office use — usually this size is sufficient for non-specialized printing.
A6 — 105x148 mm (a quarter of the landscape sheet). Printers of this format are usually designed primarily for printing photographs — the sheet size is approximately equal to the size of a standard print of 10x15 cm.
A8 — 52x74 mm, an extremely miniature format, which is 1/16 of the popular A4 (comparable to the size of a standard business card — only a little shorter). It is found mainly among portable printers (see "Type"), including models with specific printing tech
...nologies (on special paper without the use of dyes).
Note that the media format specified in the specifications is rather conditional: many printer models do not have length restrictions — the main thing is that the media fit into the width, and in some devices the actual maximum size is somewhat different from the standard sizes of a certain format.Photo print
Printer print speed in photographic (highest) quality. Unlike other similar parameters, in this case the speed is usually indicated for a 10x15 sheet (A6, the most popular format for photographs). In addition, photo printing speed is not expressed in pages per minute, but in seconds per page, because. printing takes a lot of time. This option is worth paying attention to if you plan to
print photos frequently.
CD print
Ability to use the printer to print directly on recordable optical discs (CD-R/RW, DVD-R/RW). Thus, after recording a disc, you can put on its non-working surface (non-mirror side used for inscriptions) an inscription or image as you wish. Often these printers come with software that makes it easy to create layouts
for printing on disks. Please note that only specially designed discs can be used for printing.
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.
